We booked Floats for my 30th birthday trip to Rotterdam as it looked like an interesting place to stay. When we arrived, the room we were booked into was having some maintenance work done so we were given another terraced room directly overlooking the reception, so we decided we would wait for the original room to be ready. This took around an hour in total, and we were offered a free drink, however all guests are offered a free welcome drink so this did not feel like extra compensation. The receptionist was friendly enough, she acknowledged it was my birthday when checking my passport but no extra effort was made, even while we wait for an hour for our room to be ready.
On the morning we checked out the receptionist knocked on the door to hurry us along, which we thought was quite rude.
The room was nice, the terraces overlook each other so be aware of this when booking. It lacked some basics like hair conditioner. Our room was also close to the street so there was some noise throughout the night.
Location was really good for us to walk everywhere, and about 5/10 minutes from the tram. Overall it was an okay stay, but we wouldn't choose to stay here again.
