We loved our short stay in Riga. Kirils' apartment was a big part of it : despite our first surprise at the look of the building, Kirils' place was spotless clean, gorgeously arranged (it seems to have been completely remade as new a very short time ago), very well equipped, not very far from the old center and good restaurants, and with buses immediately accessible down the street. It was also very quiet, which allowed us to relax after long days of walking around town.
Kirils was very kind and always available, before and during our stay. Also, the little map of the neighborhood he prepared with places to eat or shop was a nice and useful attention.
We would not hesitate to go back there if we came to visit Riga again!
