The host, Stefan was respectful and helpful and did not bother me. The location is great - there's a tram stop 1 min from the building, the transport is regular and in less that 15 minutes I used to reach wither the centre or the Medical University. The metro is also at 10 mins' walking distance, so the airport is not hard to access (less than an hour, several euros), although there's one change of trains. As I was there for a training, related to my work, the good internet speed was a big advantage.
