We stayed in one of their 2 bedroom apartments. It had plenty of room for 4 adults and a nice little kitchenette if we wanted to prepare food. The Wi-fi was OK, but the cement walls sometimes kept it from working well. It was clean, but they didn't (or just don't) clean the apartment or replenish towels daily, so you have to ask them if you want that. Minor issues were
1) heat-they have radiators in each room, but they weren't working when we got there, so we spent a very cold first night there. The next morning we asked about it, and they literally fired up the boiler for the radiator. The rest of the stay the apartment building smelled like campfire..but it worked and we were warm.The smokeyness didn't bother us, but if someone is sensitive to smoke it might be a problem.
2)Beds are pretty firm, not uncomfortable though. However, the beds in both rooms sunk down in the middle. We used one of the small drawers from the attached headboard to prop the bed up from underneath, problem solved!
Overall, beautiful and quiet location. Pool was not in use due to weather, and if there is a sauna they didn't mention it or show it to us.
Many good places to eat in nearby towns. We did not eat there as they seem to only serve food at certain times, and communicating in English was a little struggle. But very nice and they were helpful when we brought up our concerns, and we would stay here again.
