Me and my dad spent 3 nights in Seville at the end of March. Fernando was very helpful during our stay while we had difficulties with finding a parking spot and later on with wifi (which ended up working but very slowly). The location of the apartment is good, about 20 min walk from the Alcazar and there are a lot of restaurants and bars in the neighborhood so you don't have to walk much in search of a meal, but can also be very noisy during weekend. The apartment was well equipped and had everything needed for a nice stay in the city, including a washing machine! We had bad luck with the weather and during a rainy weekend in Spring the apartment is very cold. Luckily there was a small heater and blankets to keep us warm. I would recommend taking slippers with you just in case!
