This is an amazing place and you should definitely come here! Right in the middle of the centro historico, so you’re close to basically anything. The apartment is very nice and contains everything you need, both for a short as well as a long stay. I can totally imagine settling down for a week or even more! Also, communication with Nacho works perfectly fine!
However….being in the city centre comes with some difficulties. If you’re here with a rental car, I do have some suggestions for you. Avoid getting into the narrow streets because it’s not a pleasure driving/navigating here. Parking is also difficult and not recommendable on the streets if you have a rental car. Try find a parking lot somewhere outside of the city centre of go to a paid parking, because in the city centre it will cost you 25€ a day.
Also: if you don’t want to wake up at 8 o’clock because of church bells, this might not be your place since you’re next to a church.
Anyway, this didn’t stop us from having an AMAZING time in Seville and I would definitely come back to Nacho’s place!!
