We had a lovely stay in Marta's flat - the location was perfect for our time in Seville. The airport bus drops off and picks up at the Torre del Oro which is just across the bridge making it very easy to get in and out from the airport. The old town and sightseeing spots are all very walkable from the apartment.
The apartment itself was very comfortable and clean - there is air conditioning, a powerful shower and a good bed. The balcony was a great bonus for breakfast. There is a big supermarket around the corner, and two smaller shops nearby too for breakfast/lunch bits. The coffee machine was put to good use too. There is a bit of noise from the surrounding apartments, but overall the building is very quiet at night (we weren't there much during the day).
We were very pleased with our stay and would absolutely recommend this apartment to anyone looking to visit Seville. Marta was responsive and helpful in all of our exchanges - thank you again for having us! :)
