Apart from the travel stress to get there from the Airport...everything was fine, there was no real problems at all, Our host was very friendly and helpful (via phone).
One thing I must mention though, is that the check-in is a neighbour giving you the key...the neighbours buzzer was not working when we came, so I waited for someone to come out of the building and then went up to the floor and knocked/frantically waved until they came and gave me the key (access to front doors are also key only entry) probably the buzzer will be repaired by the time others want to check-in, but please bear this in mind in case there is not answer... and I hope you will enjoy your stay like we did!
