The apartment we stayed in was really nice - everything was clean (nice white sheets and towels), it is really pretty inside and the location is really great for sightseeing, you can get basically anywhere from there within 30 min. However there is one issue that greatly influenced our experience - there is no way to open the only window of this apartment (I was told it was due to safety reasons). Opening front door doesn't make the difference either - the flat is located at the end of a long narrow corridor with no windows. It caused humidity to increase significantly which caused us some discomfort. The owner was really responsive when I reported this issue to them, which is good, but they didn't solve it.
