I moved my piano when we moved our family to NJ 2 years ago, but while we took care of all our…read moreother belongings we never had the piano serviced or tuned. (Pretty aweful considering my wife and I are both classical musicians). Even worse this was the piano my Grandmother gave to my Grandfather years ago for their anniversary. I felt like a terrible steward of this instrument...BUT one visit from Guillermo changed all that! He is a lovely guy with huge interest and love for classical music and pianos. He treated our Acrosonic upright like it was a 9 foot Steinway Concert grand at Carnegie Hall! He worked with so much care and precision. He even did a double tuning for the same price to insure it would recover well from the lack of care. He wouldn't quit until I (and he) were satisfied with the sound and temperament. I couldn't feel better about his work and I couldn't be more confident about caring for this family heirloom instrument having Guillermo as our tuner! I HIGHLY recommend Flip Those Keys if you're looking for top notch work on your piano that comes with a charming and personalized touch! Thanks Guillermo!

I contacted Guillermo on a Thursday night and he made an appointment with us on Friday! Well, within a few hours- he took his time and paid a lot of attention to detail that was obvious- and our piano sounds AMAZING now!! I would highly recommend Flip Those Keys for great piano tuning service!

I had an outstanding experience purchasing my 1992 Yamaha G5 grand piano from Piotr. From start to…read morefinish, this was easily one of the best buying experiences I've ever had. Piotr personally restored the piano himself--installing new strings, new tuning pins, full regulation, and hammer voicing--and the result is incredible. The piano has a rich, powerful tone and a responsive, even action that easily meets the demands of advanced repertoire. As someone who used to play at a virtuoso competition level, I was very particular about touch and control, and this instrument absolutely delivers. What really set Piotr apart was his dedication and transparency. He patiently answered all of my questions, sent multiple detailed videos, and even shared a magnificent performance of Chopin's Fantaisie played by his wife so I could hear the piano's full expressive range. That level of care gave me complete confidence before purchasing without being able to see or play the piano in person. Delivery was just as impressive--Piotr handled everything himself and safely delivered the grand piano to my home. It's rare to find someone who can truly do it all: piano restoration, regulation, voicing, and delivery, all at a high level. I grew up playing only Yamaha uprights and always dreamed of owning a grand piano. Thanks to Piotr, that dream is now a reality. He's not just a seller--he's a true piano technician and pianist who genuinely cares about matching the right instrument to the right player. You can tell he's passionate about his craft and takes pride in every piano he works on. If you're looking for a high-quality restored piano, I highly recommend reaching out to Piotr. This was a seamless, professional, and genuinely enjoyable experience.

I am a professional jazz pianist, and I had a grand for 25 years that has seen the last days of…read moreit's life. I had been on the lookout for my dream piano, a Steinway B, and thought it wasn't doable. Then a friend from NYC recommended I connect with Piotr in Philedelphia. I was very nervous about a piano purchase from Philly, as I am in Boston. I had to play it to see if I loved it, because it's a life investment. Piotr told me what was done to this Steinway A3. Pin block ten years old, strings 10 years, and the rest fully restored by him, using genuine Steinway parts. Well, I said what if I don't connect with it? Your gonna take it back? He said yes, so I agreed. He drove here, set it up, I played it for hours, and then said I loved it. He took my K Kawai in trade, and there you have it. He fully guaranteed it his work. Don't know what drives this person, but he is quality like I've NEVER seen. I could not recommend Piotr and Opus piano more. Go there! Only there! They are old world quality, and connection. It doesn't exist anymore, yet, I was lucky enough to find them. Now I have my last and final piano. My Steinway A3, not a B but just as good in my opinion... I have had the piano for about 2 and a half months, and it's amazing... He was right. I loved it. Thanks Piotr
