We stayed there in September 2019 as a group of 5, and it was really good.
The apartment has 3 bedrooms, each one is separetly accessible. Very comfortable beds. Location is excellent, near some of the landmarks in the old town, and a few minutes walk from 2 subway stations. It can get a bit noisy at times but closing the windows solves this issue.
We had everything we needed. The kitchen has modern amenities including a dishwasher and a modern electric stove. Nice bathroom, on demand hot water.
Richard the host was very responsive and helpful, helping out and giving some very useful tips and general information.
Would definitely recommend this place for groups.
