We had a perfect stay! Location is excellent, close to everything in Old Riga, to the bus and train stations.
Very kid-friendly, really a lot of space and air.
Kristiana is a great host, always ready to answer our questions!
We stayed for the first week of October so there was no central heat and the appartment was quite chilly. But we came prepared (warm home clothes for us and fleece costume for our child) so this was not a problem.
On the last day of our stay (of course!) the heat was on and the appt became extremely warm and even more comfortable.
