Lovely apartment. Didn't meet Steven, but was welcomed by Katarina, who was really helpful about where to go and how to get there.
Apartment is in a nice safe area, with 2 stations located within a 5 minute walk. However we walked into the centre most days which took us around 25 minutes. The apartment is located north of the river and many of the attractions are towards the south, but the walking through the 1st district is lovely.
The apartment is a good size, with everything you'll need, and really warm! It is on a main road, with some road noise but this did not bother us.
