The apartment is really clean and spacious, and has everything you need to live comfortably. We were there for a whole week to attend a conference, so it is very nice to have a big apartment to come back to. Vir is very friendly and responded very quickly and provided a lot of information about places to visits and restaurants to eat. It is about 20 mins away by tram from Guggenheim and is in a residential area. The only drawback is that the apartment is surrounded by construction site, so during the day, the construction noises can be loud and a bit annoying. And the tram stopped after midnight, so if you enjoy nigh life, it will be a problem coming back. Overall, we enjoyed the stay, and the great view from the back balcony.
