The appartement was really beautifull. The 2 rooms are large and clean. The beds were okay. The kitchen was a bit small. Only one person could cook or whash dishes within. The heating and cooling system (heating in our case) work very well. It was great to use the terrasse for a late morning coffee, with a splendid view around. The area was perfect, just in the middle of the 16 and 17h district, 10 minutes to walk to the Cathedral and the Alcazar. Every site in the inner city was to a walking distance. Taxis are quite cheap anyway. We did not met Carmen but her associate or employee Javier who was nice and helpfull.
Little things could be better and I'm sure the will be in the future. There was no writtten personnal book as there is usually in AirBnB flats. The Italian moka pot couln'd work because the joint was out of service. There was no teapot either.
But the appartement is anyway absolutly gorgeons. I recommande it.
