My family had a very pleasant stay.
The location couldn't be better as it's served by all kinds of transportation to take you across the city. The neighborhood is nice, full of restaurants, supermarkets, local cafes and a park.
Even though the apartment is on the second floor we didn't suffer much, but beware that after the hole day of sightseeing you will still need to climb those stairs ! :D
Communication with the host was easy and fast. We had an issue with the heating system during the New Year's holiday and it was all solved in the same day.
Flexible check in and out, which was very appreciated since my family was coming from/to Brazil.
Definitely recommended.
