We had a fantastic time in Sevilla; and it was also, because Rocio's flat was so great: clean, well equiped (we came with our baby and a high chair and toys were provided!) and lovely decorated. It is central, has a very nice neighborhood, many bars, supermarkets around the corner and Rocio gave us exellent recommendations for Tapas and sights.
The communication with her always was fast and easy.
One tiny thing is that it can be quite noisy at night on the streets.
All in all, we would come back again any time!
