Great place. Very clean cosy apartment, true to the photos. We stayed in a 4 person flat with two, which was ideal. Would be a tight fit for 4 though, especially with suitcases.
Kitchen and necessary appliances (including dishwasher and washing machine) were all in very good state.
Walls are very thin though and people in the halls tended to make a lot of noise...
15min walk to Guggenheim.
25min walk to Old Town (via decent neighborhood 😊)
Would recommend and stay here again.
