Check in was not smooth to say the least. There was a keyless entry that you use an app for. I didn’t get those instructions until after we finally got into the flat 45 minutes later. We were only there one night so it was fine but keep in mind it is on the 3rd floor-no elevator. It is in a busy square and it is loud all night. Between the street noise and the garbage trucks, we hardly slept. The building is old and very cool and the square is fun, until you want to sleep. The mattress and pillows were very comfortable but the bed squeaks loudly with literally every little move. Not a great stay.
