My girlfriend and I visited Seville after many friends and family raving about the city. Nacho's apartment appeared to be located perfectly for our needs. 5 - 10 minute walks from most of the main sights. The apartment itself is in a quiet area and has a lovely balcony that we made use of for some evening drinks. Everything was as described and very clean.
As a host Nacho was always very quick to respond and easy to get a hold of. Overall a very enjoyable stay and experience.
