We had a great stay in Seville. Pilar's place is very large, has two bathrooms and air conditioning in all bedrooms.
The kitchen lacks some utensils but I'd find for short stays and we were there during a heat wave! Pilar provided us with pool passes which was very kind.
The apartment is quite far away from central Seville so you'll need to take the bus or drive in. There is a car park underneath the apartment available.
Overall very affordable stay in Seville.
