    Visited the Poseidon SPA for the first time for a little R&R so close to home in St. Augustine and so beautiful. It is attached to the historic Casa Monica Resort & Spa, the Kessler Collection hotels, and the level of professionalism and skill at this spa is outstanding. From the friendly greeting upon arrival, to the well appointed sitting rooms and luxurious robes, this place exceeds expectations at every turn. I had the Poseidon signature massage and opted for the scalp and face massage. My massage therapist Tiki was awesome, and after she talked me through the services I'd signed up for, she also paid special attention to the problem areas I had mentioned. After I was completely relaxed from my massage. With multipurpose rooms for facials, body treatments, and massages, the Poseidon Spa also offers couples room and several pedicure and manicure stations. Hair and make-up stations are available to serve bridal parties and guests attending formal events. There's also a beautiful retail boutique. I can't thank Poseidon Spa and @casamonicaresortandspa enough, it was an absolutely perfect treat, such a beautiful relaxed day. The Poseidon Spa is located at 53 King St. in downtown St. Augustine, at the Casa Monica Hotel. For more information, call (904) 819-6155 to book your appointment. ‍

    This place is perfect for a day of relaxation and pampering yourself! I came in on a Saturday evening for a Signature Pedicure, nothing fancy...I'm a simple gal. I was welcomed by 2 lovely ladies and given a short form to fill out and offered many additions to my service, they provide a menu of things you may not know you can get! I was directed to the waiting room, a dim sitting area with herbal tea and infused water offerings. (I noticed someone staying at the hotel brought her glass of wine from next door and they even got her a refill before her massage!) The room is decorated in cool blue tones with an almost beach-y feel. There are plugs if you need to charge up, abut 5 chairs and just enough lighting to help you relax. I was also offered a warm neck wrap and am beginning to regret not purchasing one for home. The ladies asked if I needed anything a few times and were very accommodating to everyone I saw come in while I was there. Great staff with awesome customer service skills! I got the best pedicure ever! No 'cheese graters' or rough pumice stones, just a real pedicure. It was extremely relaxing and days later my feet feel soft and refreshed!! I had Nancy (Naja) as my pedicurist and she's a ton of fun - admittedly, we know each other and had plenty to talk about. I trusted her to pick my color and she went with the deepest forest green I've ever seen - it's almost black. This is an on-trend color pick for fall so she definitely knows what she's doing and keeps up with what is in fashion. Of course, there are massaging chairs, bubbles in the water and - if you'd like - another amazing neck wrap (win!). It's an intimate room so you don't feel like you're in a nail barn with 40 other sheep, it's a simple, clean space with enough room for 2 pedicures at a time (and 2 manicures at the nearby stations). The spa is connected to the Casa Monica hotel, so if you are staying in St. Aug for a refreshing weekend, this is a great way to spend some of your time - maybe after walking the shops for a day or two. The prices are a bit high, but again, this is a resort affiliated spa - you are paying for the comfort and ease of walking a few feet with a glass of wine and getting an amazing service. Don't let the prices scare you, we all deserve a treat and need to take care of ourselves better!

    Entrance to spa!

    Well worth the rub down! Tiki was incredible, amazing pressure. We went all out on our time and left feeling rejuvenated!

    One of the best message I have had on a long time. Would definitely go back. Hot stones helped my sore muscles.

No intent of reputation harm was intentioned, rather to fix their mistakes and terrible service before I posted for all to see. I genuinely do not understand the high ratings for this salon after my experience. I paid $75 before tip for a "spa pedicure" that lasted barely over 30 minutes, left my toenails uneven and misshapen, and resulted in my toe being cut and bleeding. Before the service even started, I specifically mentioned that my biggest concern was being cut. That exact thing still happened. The technician used cuticle scissors on my toenails, pulled at thin nails instead of properly trimming them, left scrub residue on my legs, and sent me out the door with nails that looked unfinished and uneven. Several nails were completely different lengths and shapes, including nails that were not damaged to begin with. What bothered me even more was the salon's response afterward. Instead of taking accountability for the quality of the service, they blamed the condition of my nails from previous gel use. I had already explained the condition of my nails before the service began and she assured me it was not an issue she deals with it all the time. If my nails were supposedly too damaged to safely or properly perform the pedicure, that should have been communicated upfront instead of taking my money and giving me a result that honestly looked worse than when I walked in. I also clarified that the pre-existing chip in one toenail was NOT what caused me to bleed. The cut happened separately during the service and on a completely different toe. At this price point, I expected professionalism, attention to detail, and basic care. Instead, I left with uneven nails, a cut toe, and an email response that felt more focused on defending the service than resolving the issue. I would strongly encourage anyone considering this salon for nail services to think twice. There are too many salons charging premium prices to risk walking out with results like this.

    What an amazing experience! I cannot recommend the spa enough!
