We stayed at Maria's large, beautifully decorated place for 3 weeks. Maria arranged for pick up and drop off from the airport, gave a nice introduction /orientation to the city and responded to questions without delay. The apartment is well represented in the photos, beds are comfortable, wifi works well and there was plenty of oils/spices in the kitchen. You can hear street noise in the upper bedroom but Maria provided ear plugs (And the noise should be expected given the location).
The location is central, everything is within walking range. Seville is a great city, if my wife had her way we would be living in Maria's apartment year-round. We definitely recommend Maria's apartment!
