Wonderful and well-maintained apartment. Well-equipped kitchen and clean washrooms. Spacious room with welcome snacks :)
Clear instructions, responsive and responsible host. Understanding as well.
The only con in my experience was the heater, which was old and didn't have a working control knob. The first night was cold, as it didn't work; the host got it fixed the next morning -- then the second night it was on full (100%), so very hot. Pro Tip: Open the window to get it to a reasonable temperature.
So if you are in Room 5 on the first floor, do get it adjusted as you desire full/half/quarter/off if you want uninterrupted sleep. I've communicated that to the host, and he will hopefully replace it in the near future.
