Matthias's apartment is excellent. A very spacious and comfortable place, a lovely outdoor area in warm weather, plenty of space to relax after a long day of walking and sightseeing. Good instructions and information regarding the flat and the neighbourhood. Very good supermarket right next door, plenty of restaurants, good speciality coffee places nearby (Oslo, The Barn and Distrikt). Transport is excellent U Bahn and trams. Well fitted out, very clean. Our host was very communicative when needed, to make sure we had everything we required. We highly recommend it.
