Their attention to details: they saved us a place to park our car, they had a great common terrace to rest, read and enjoy the landscape. The apartment is very nice and well decorated, everything was very clean.
Huge TV with Netflix, the bathroom with all kinds of amenities in case you forget something, the kitchen is small but with everything you need.
Maybe the distance to the center but it was something we already knew and it didn't matter to us because we like to walk.
