The apartment is cozy, clean and well organized. We were a couple, but it could be spacious enough even with 1-2 children. It's in excellent central location - we didn't use public transport even once, although tram and metro stations are just a 3-4 minute walk. Nevertheless, the neighborhood is very quiet. There are a bunch of nice restaurant and cafes nearby - don't miss the Lucerna passage.
Martina was extremely kind and reliable, quickly responded and helped in every question we had.
We had a great time, and would definitely recommend!
