had really issues to find the right entrance... the key worked for both buildings and I've been in the wrong one (go to floor 0-3 via the jokey and the elevator but not to 4). because I couldn'tcontact the owner, who lives in the US, I knocked at some doors at 11 pm and a very charming lady calmed me down and showed me the way. the stay itself was great although the parking spot is very narrow.
