We had a wonderful stay at Cristina's place. The location is fantastic - right next to the cathedral (with a beautiful view from the kitchen) and it meant that we could pop back to the apartment during the day to have a rest.
The apartment is bright and a good size. There were four of us staying and plenty of space but it will be cosy for six. The apartment was clean and well kitted out. Communication was fantastic - easy and friendly. Everything was smooth and the apartment suited our purposes well.
The kitchen was fairly well equipped although we did not do any cooking. The showers are nice and strong. I appreciated the eco shampoos and soap.
If you are going during the winter, just note that the tiled floors will be a bit cold so bring some slippers or extra socks. However, the heating the apartment was great so no overall problem.
