The room (as well as the bathroom) was nice and clean. My bed was comfortable and with good size - my friend who slept on the mattress didn't complain either. Andrea had put some welcoming waffles on the bed - that was very nice of her :) The house was super clean, tidy and decorated with a very good taste. As for the location, it was just 10-15 minutes by tram/bus and the tram/bus stop just outside your door. Although it was located on a main road, the room was quiet (but also the road wasn't that busy).
Andrea was very nice and thorough. I could hardly tell she was in the house! Also, she's reliable; I was 100% sure she would reply promptly to my questions, even after I left, when I thought I had forgotten my passport in the room :)
I highly recommend this place, but only if you're a person that respects other people's houses and boundaries.
