Apartment: this was our first time staying in an Airbnb that is used as a primary residence. It was like staying in your uncle's bachelor pad. Not a beautiful place to relax and spend time, but a good place to come back to sleep that is safe, comfortable and spacious. A big bedroom and two bathrooms were a plus. It was clean and the pictures were accurate.
Location: it's not walkable from anywhere unless you really love to walk a lot. Bus was about 10 minutes from the central station, other sites were 20-30+ minutes by bus and tram. This is a residential area and there isn't a lot close by, so this is a quieter neighborhood away from the tourists.
Communication was very easy, and we were pleased with our stay overall.
