Arturs flat is really nice and in the area you wanna stay in Riga. You can spend infinite time just walking round the neighbourhood and looking at all these wonderful "Jugendstil" houses. The apartment itself is like you can see on the photos. I was staying there for a month and did not miss anything. Walking to the old town takes about 15 minutes passing through two nice parks.
Artur was really friendly and even picked me up from the coach station. Also my bus was late he took the time and showed me some good restaurants in the neighbourhood. Definitely recommended!
