We had a great time at Martin's place. Martin is a great host that has a lot of tips about Vienna but also respects your privacy. The place is good (pictures are accurate), quiet, clean, and contains everything you need for cooking, showering, sleeping, etc. It is also nice to sit in the yard when the weather is nice! The place also has good connections to the city center and there are lots (!) of supermarkets nearby. If we ever come back to Vienna, we will definitely consider coming here again!
