The apartment is in a great location and is very nice. We had an issue with centralized heating and the host was very responsive in providing alternate heaters, however we expected air conditioning to be available in all rooms instead it is only available in the living room. Hot water is provided by a small boiler that takes about 40 minutes to get fully charged and is barely enough for two showers. Given the apartment can accommodate up to 5 people I think this is not enough to make the stay comfortable. So I would not recommend this for more than 2 people.
The place is very cozy otherwise so it was a bit of a let down. Everything else was great.
