To clarify the setup here: You will be staying in a very clean, large apartment, with several bedrooms. This room comes with a key to use its own dedicated bath / toilet room, which is down the hall. The other guests share another bath and toilet. There is a common area with a sink, fridge, table, coffeemaker etc. I don’t recall if there was a stove or microwave.
The apartment is spotless, the building itself is ancient, and the street looks a bit run down, but that is most of this city. It is a very convenient location, and we would happily stay here again.
