I spent five nights at the Mercure Berlin City along with the rest of the tour group I was…read moretraveling with. ( had previously visited Munich and Nuremberg.) It was a super mixed experience. I'll start with the cons.
The hotel room was quite small. It had twin beds that were awfully close together, and there was no good space to put a large suitcase. There was no real closet, either - just a small area to hang up a few items. I'm still wondering who designed the room and included a strange window into the bathroom. (There was a shade on the inside, so we were still able to have privacy). There was neither a fridge nor a microwave in the hotel room - perhaps these are not as common in Germany as they are in the United States?
The fire alarm went off the first night of our stay. As the nearly 30 people in my group and all the other hotel guests descended towards the first floor in our pajamas, I wondered what the cause was. As we exited the hotel, we immediately saw - and smelled - multiple cigarette smokers right outside. I cannot be sure, but it seems likely that one of them (or another guest) set off the alarm by smoking inside the hotel.
Lastly, while using the lobby men's room one day, I discovered it was out of soap. I walked to the front desk and notified the clerk, who thanked me for the heads-up. Unfortunately, there was still no soap the next day.
As for the pros, I'll begin with the food. The breakfast buffet options were abundant. There were eggs, meats, cheeses, croissants and other pastries, yogurt, fruit, vegetables, cereal, at least four bread options - all super fresh - multiple jams, three kinds of honey, tea, and a coffee machine with a variety of choices including hot chocolate. There was also plenty of time to enjoy breakfast, as the breakfast hours were quite generous.
More positives: the hotel is close to both public transportation and the REWE grocery store. There was a safe in the hotel room where I kept my passport. The hotel staff stored my entire group's luggage in a locked room before our official check-in time, and they kindly stored mine for several hours after I checked out. Since there was no fridge in the room, I asked if they could store my dinner leftovers in the fridge a few times so that I did not have to throw it out or let it go bad before I could finish it, and they obliged.
Finally, the hotel staff was very friendly. Every day - sometimes multiple times a day - I would ask the hotel bartenders if I could trouble them for some ice. They would take my insulated water bottle and fill it up. Back home, I drink cold water all year long - you better believe that in Germany, I was in need of ice in August!
If you're considering staying at Mercure Berlin City, just be sure you know what to expect!
