Amazing location and an enjoyable stay overall. The host was always quick to respond to any and all questions.
Three of us stayed for about a month. I think the longer stay made me long for some more thoughtful touches for functionality throughout the apartment. The furnishings seemed a little bare as the stay went on. Having one bath towel per person for the whole month was a bit inconvenient. The elevators are really busy at random times as mentioned in other reviews. The record was a 35 minute wait for the elevator when I was trying to meet a friend for lunch around the corner. It's not bad to this extreme too often, but just a tip to plan ahead if you're trying to get somewhere at a specific time.
The sauna was pleasantly hot and working during our entire stay.
