A spacious apartment with a lovely kitchen, though pretty spartan -- no curtains, no art, no fans, no extra sheets, towels, or blankets (we weren't given hand towels and had to request sheets to make up the third bed). This makes it hard to feel like a comfortable place you are staying at, and more like an impersonal hotel room.
As others have said, the bathroom is a big drawback. Considering how large every other room is, the tiny size is so strange. There's an empty closet in the living room larger than the bathroom! It is a challenging room to navigate, and the frosted door does make privacy challenging if you're staying in any configuration other than a couple.
