We stayed at Peter's place for a couple of days in January. The house is very well heated!! It is cozy and well furnished, perfect for two people. We've found everything we needed. Peter is helpful and nice! I can really recommend his apartment, which is located in one of my favourite areas in Vienna. Close to the 7th district Neubau (which means lots of Cafés, Restaurants, second-hand shops and bars, which are open at nights too) and Vienna 1st district, the historical center, which is less than 10 minutes away by tram! Enjoy your stay!!!!
