We haven't met Alex, but he arranged everything perfectly. He communicates promptly, which is very good. The apartment is very unusual ground floor place, but it has all the comfort a treveller needs. It is clean and feels warm. Concerning the arrangement of the apartment - there are two double beds there, One of those in a bedroom at the backside parto of the flat, one in the living room - consider this if you are traveling and absolutely need some privacy. There are other 2 - 3 sigle beds that can be used in various places of the apartment. Although the place is a ground floor space and the largest part is facing the street, we found it very calm. The location is excellent, S-bahn station is just a few minutes walk away.
