Peter was an excellent host, in every way. He was prompt with his emails, very helpful and flexible when our flight arrived at 5 am, and was even able to book us a private car to pick us up from the airport. The flat was very comfortable and equipped with handy conveniences (toilet paper, dish soap, etc) apart from the usual towels and sheets. The neighborhood was great, close to the metro and major bus lines (including a bus to the Hbf train station) as well as the fun Naschtmarkt and pedestrian shopping street Mariahilferstrasse. In all, it was a great experience and wish we could have stayed longer!
