We travelled as a group of six friends to this apartment and had a great stay. There was more than enough space (although a slightly unusual layout of one bedroom). Having only one bathroom concerned us before arriving, but wasn't a problem at all.
The location was great for the old town and train station. There were plenty of bars and restaurants nearby, and it was great to have a drink on the terrace in the evening.
Would definitely stay here again if we come back to Riga in the future.
