I spent 4 days at Rafael's with friends, and we had a very good time;
The communication with Rafael was very quick and simple. He gave us all the informations we needed before our trip, and had someone to welcome us at the apartment when we arrived, to show us the place and give the keys;
the aparment is ideally located in Sevilla city center. It is very well furnished, with all the amenities you would need, such as toaster, coffee machine, hair dryer...
thanks a lot!
