Excellent location, close to everything, quiet (no windows towards street, only inner garden), warms up easily, small and practical kitchen, comfortable beds, awesome shower pressure. Negatives are a bad experience during check-in (cleaning service did not clean on time so we had to wait until they were finished with our toddler), a terrible washing machine that is so noisy you'll think things are breaking every time you wash, and the host could have been more responsive - very slow to reply, never answered phone calls.
We also made one mistake - forgot to drop the key off, but we sent it back immediately on arrival home.
All in all, we recommend the apartment, it is a fantastic base to explore from with plenty of kid friendly and stomach-friendly places around, shops, and metro stations / bus stations to take you anywhere.
