We had a great stay at Pilar's house. A little smaller than we expected from the pictures, but comfortable all the same. Our train to Seville was delayed but Pilar stayed in contact and was there to meet us when we arrived. On top of the room she provided fresh fruit and tea for breakfasts, bottles of water, maps of the city and fresh towels and shower gel.
The house is walking distance to all the main attractions in Sevilla.
Pilar stayed out of the way and wasn't home much, but was contactable by phone if we needed her.
I would recommend staying at Pilar's so a simple, comfortable stay.
