We had a lovely stay in Vienna. The apartment is in an old building, but has an elevator, and the house was clean and comfortable. The rooms are very spacious. We were two people, but it could very easily fit more. The location couldn't be better: easily reachable by public transport, yet far enough from the center to avoid the more expensive prices. There are good restaurants nearby, as well as bakeries, markets and basically everything we needed. Nick wasn't in town, but was very helpful throughout our stay, especially concerning our late hour check in and early hour check out. I would definitely recommend Nick and his nice apartment to everyone!
