Don't stay there in winter! First, I'm not someone who's generally cold and neither is my spouse!
This apartment is located in the lower ground but I didn't know this before. It's unbelievably cold. The electrical radiator is useless unless someone needs a hot back and cold front while sitting at the table directly in front of it. It's impossible to obtain a "cozy" (as written in description) environment. The warm water supply is so poor it's not possible for 2 people to wash their hair one after the other. Unfortunately I had to experience this myself when I had to rinse my shampoo off my long hair with ice cold water (after my spouse had taken a shower for 5-10 min).
Actually, the apartment is so cold (and clammy) that the towels didn't properly dry within of 24 h.
Speaking of towels, we were provided only two "big"/bigger towels and one small towel for two people for 1 week! Also they were thin and def. not "hotel quality". Sofa is full of weird stains, windows can't be opened.
