A great place to stay; within walking distance to the main attractions in Riga. Location is very quiet (even with a the main road just outside).
Communication with host was superb and very responsive to all my questions.
For short stays, this would be ok for for four people, but long term maximum is two (if not one - in my view).
Long term stays have a cleaning fee every two weeks at 25euro; change of bedding, towels, tea towels and a full clean of the flat; in fact, this is a great deal as when you walk in, it is how you arrived on day one. So, make sure you factor this in to your costs.
Overall, a great flat, great location and great hosts. Would happily stay again.
