The Green Street residence is tastefully decorated, comfortable and cozy. It is only a 3-4 minute walk to restaurants, and the magnificent Art Nouveau district known as the Quiet Centre, and beyond that, the gorgeous ribbon of parks near the Old Town. We used Taxify to get around. It was cheaper and more convenient than buses or trams. For example, a 10 minute ride to the Old Town t cost around 3 euro. Riga is a city well worth the visit -- full of great architecture, consistently good dining, and one of the biggest food markets in Europe.
The only negative about the rental is that it is on the ground floor, and faces a parking lot. If you do not have the blinds pulled down, there is not much privacy.
