Location location. We only used the metro once to get to the airport the rest of the time everything was walking distance.
The apartment was clean and well equipped with everything that we needed.
The checkin was great and we even check-in an hour earlier. There is a shop and bakery close by where you can get coffee and baked goods for breakfast.
We really enjoyed our stay. Do note that the apartment is on the 4th floor without a lift and is something to keep in mind it you have small kids or lots of bags.
