The apartment is in a great location, very central and walking distant to most attractions. It is spacious and very clean. We did not meet Anjela but her friend Elena was available to help us get into the apartment.
Because the apartment is close to bars, restaurants etc. it can get quite noisy, as there is live music. However, this stops at 11pm. This didn't bother us as we were out enjoying the music, but I'd recommend ear plugs if you are a light sleeper. Riga is beautiful and we recommend doing the free walking tour, and visiting the Art Nouveau district around Elisabetes and Albert streets. Also a trip to Jurmala Beach if the weather is good is well worth a visit - 30 mins on the train.
