My wife and I stayed at Ralf's apartment and everything was perfect, from check in to check out, everything happened according as agreed. Ralf provided the shuttle service to the airport / apartment. The driver arrived at the scheduled time, on time. It was all very easy, both on arrival and on departure. The apartment is very cozy, nicely decorated, clean and tidy, very comfortable bed, kitchen with everything the guest needs to prepare coffee and small meals, the location is very good with easy access to public transportation. The person who received us in the name of Ralf (can not remember her name) was very helpful and kind, gave us useful directions and even lent us a card that is required to use the subway or bus. Anyway, our experience of staying at the apartment Ralf was excellent. I recommend 100%.
