My stay (6 night) at Boris apartment was comfortable. U-bahn stops (U6, U4) are 10-15 minutes walk and a bus stop to the city centre and to Meidling railway station is less than 1 minute walk. Small and large supermarket are also close. I had a problem with the hot water boiler that stopped twice, but Andreas (Boris' assistant) answered immediately to my phone call and fixed the problem in few hours.
