Great location; quiet neighbourhood and short walking distance to all highlights (1 min to supermarket). Spacious flat, responsive owners...
The only downside: Walls are too thin, you can almost hear all noises (sneezing etc) from the flat next door. Bear this in mind especially if you're not tolerant to (or travelling with) kids who can be a bit loud.
Everything was clean, a good point, that everything is well organized around the process. Location is close to the city center, and it was pretty comfortable for the family of 3.
