We spent 4 weeks at Apartamentos Campana in July. The "automatic" check-in system worked extremely well given our flight delays. The concierge was very responsive and helpful, for which we are very grateful: we asked for a work desk for my husband and one was provided very quickly; we asked for an extra drying rack and sheets (before figuring out that the washer is a combined washer/dryer) and those were also provided promptly. The concierge even printed out our Cathedral tickets for us and he was very patient and friendly with the 3 kids (ages 9, 10, 11). The responsiveness and willingness to help (always with a smile) makes Apartamentos Campana one of the best airbnb/vrbo place we've stayed in so far.
The apartment was very clean, well equipped, and comfortable. The rooftop garden was a big hit with the kids -- with the heat in the afternoon, the little pool kept the kids active without being overheated. The location is amazing - walking distance to all the attractions of central Seville, Triana, bus and train stations.
