Nice and quite place with direct access to bus and tram (both stops are within 100m). S-Bahn station is good 5 minutes walk. The same amount of time you'll need to get to Spar grocery store.
Additional bonus is parking spot in vicinity- building next street. For some it might be a bit narrow but after a few tries you'll get used to it. When getting out remember to pull the red rope inside the garage to open the entrance door since you don't have a remote. It's hanging next to old white Mercedes!
Boris was very responsive. I got his replies within few minutes.
Spending a month there was a nice experience!
