The apartment was very central, nicely restored, quite small though and only suitable for couples. The lift is perhaps the smallest in the world as it says maximum capacity of 3 persons. Yet we were grateful for it as we had kids and climbing four floors would have been a challenge. The air conditioner mainly cools the livingroom. The noise from the street is very nicely eliminated once you close the windows, which was impressive. We could still hear the stomping from the floor above us, but we have kids so we didn't mind that too much, except when that woke us up earlier than planned.
