My girlfriend and I only stayed at Stefānija's place for a couple nights, but we were very happy with our stay. We arrived in Riga in the middle of the night and she made sure that we were able to let ourselves in despite nobody being home at that time. Stefānija was also super quick to answer any queries we had and offer plenty of advice.
The flat is beautiful and very well located in an interesting building and part of town. It has everything you might need, is very clean and comfortable, and with the bonus of 2 very charming cats!
Although we didn't get to meet Stefānija, we did meet her mother, who made sure that we were comfortable and had everything we needed for our brief stay.
