Had a very pleasant stay. plenty of space for the two of us. Only experienced some noise from downstairs untill early morning (6/7 am) where they apparently where having some techno party or so, but it was a festive weekend in Riga, so this might have been an exception. The noise was also not really loud so we managed to sleep, just want to mention this for really light sleepers. The shower is a bit small, but the water is warm. The location is perfect with the apartment located on the first ( they call it second floor in Latvia) floor on a quiet part of old town, with everything in old town within a range of 5 -7 minutes and Kalku iela, the main street in old town, just a minute away. Communication with Kristiana is very convenient. Kristiana was sick and couldn't check us in herself, so she left the keys in a sishabar right across the apartment, vere pleasant.
Would definitely recommend this place for a few days for a couple. Price quality is very good for Riga's/old town standards
