Stefan's place was the perfect choice for us. It was a great location to explore the city on foot, by bike, by bus and underground (bus stop and underground station (U4) are close to the apartment). Also the Naschmarkt with its food stalls and restaurants was just a 3-minute walk away. Not only the location was great, but also the apartment itself. Clean, well-equipped, nice-decorated - and a lot of "extras" were provided (tea, tissues, Oil, vinegar, salt, etc. - we especially loved the espresso :)). All in All, great time - great place.
