We stayed seven nights at Peter's flat in Vienna and I could not recommend it more. We very comfortable as a party of three, though it could accommodate 3 couples with equal comfort. Everything was clean, the kitchen was well stocked for cooking meals and keeping things clean; the dining and living areas are spacious and relaxing. The en suite washer and large washrooms are a definite plus. Access upon arrival was smooth, and communication with Peter was easy and prompt. Windows in the living room look out over one of the market squares, which is surrounded by typically amazing buildings. The flat was quiet and felt secluded, but was a few minutes walk from the U1 and U3 lines, and from the shopping and tourist areas near the cathedral at Stephansplatz. Peter's flat exceeded expectations and I would stay there without a second thought, fives stars in all respects.
