I spent 3 weeks in Marita's flat. It was a great experince, I would definitely recommend her place if you want to stay in Riga for a longer period. The flat is not in the city center, but it can be easily and quickly reached by public transport. The neighbourhood is unique thanks to the wooden buildings and there are grocery stores and cafés/restaurants around. The flat and the building is clean. Although I did not meet Marita in person, whenever I sent her message asking about something she replied very quickly.
