We had a wonderful trip in Sevilla. We didn't see Ignacio himself but Manuel (his partner) was very helpfull. And he gave us very good advises to visit, eat, drink or even "tapear".
The apartment was nice and clean with all you need : towels, bathroom packs with shampoo & shower foam, heater,... We just had a problem with the boiler but Manuel solved it very quickly and he gave us a bottle of wine to apologize.
The situation of the apartment is perfect : near the city center but in a quiet neighborhood. We've visited the whole city on foot.
Thanks again :-)
