The apartment was lovely - very central but so quiet. Although the entrance was on a busy main road all the rooms were at the back overlooking two quiet courtyards. There was no road noise at all! Everything was very clean, and the beds we used were comfortable. Communication with Sandra was excellent and she met us outside the apartment when we arrived, gave us helpful information and arranged a taxi back to the airport for us. The Nespresso machine was a bonus.
One thing worth pointing out though is that the listing is incorrect in that the single beds can't be made into 2 doubles; 3 of the singles have a wide wooden surround and if pushed together leave a 6" gap between them. The 4th single appeared to be a folding metal bed. Also, the "welcome kit" for bathroom and kitchen consists of soap and 1 dish washer tablet. You'll need to bring everything else including cleaning cloths, shower gel, tea bags, etc.
These minor things weren't as problem for us and we thoroughly enjoyed our stay in the apartment and would definitely book again.
