We stayed in Clara's apartment for 5 days over New Year. The apartment is in a brilliant location very close to the Cathedral, Giralda and the Real Alcazar but in a quiet street. The apartment is one floor up from the street. Clara was fantastic to deal with and gave us very clear details about how to get to the apartment. We arrived late evening by plane and Clara's friend Patricia met us at the apartment and gave us very clear instructions in English. It was very cold in Seville during our visit and the heating worked very well. The apartment is beautifully decorated and very clean and the beds are very comfortable. We were 2 adults and a teenage boy and there was plenty of room for us all. There was a 4th trundle bed as well if required. Clara left very detailed information about shops, restaurants, transport etc. and a map. The wi-fi worked well and the water was hot.
The only minor negative about the whole stay was the water pressure in the shower.
I would heartily recommend Clara's apartment to all.
