I spent just about three weeks at Sergey's and Polina's place. It's an excellent apartment for a long-term stay, but it would also be great for shorter trips. I thoroughly enjoyed staying in their apartment--it had everything you'd need for cooking your own meals, the bed was very comfortable, and the whole place was spotless. Sergey and Polina were always quick to respond to the few questions I had after check-in, and they had some great recommendations for things to do in Riga. I really liked the neighborhood. It's got plenty of grocery stars, bars, etc. close by, and there's a chocolate factory just down the street as well. I would absolutely stay there again if back in Riga.
