We had a lovely time staying at Carlos' place. The best thing about the apartment is that the location could not be better, it is right in the centre within 5 minute walking distance to all the main sights and amazing restaurants, yet the street itself is quiet and feels very safe. We loved the terrace which had a beautiful view of the Giralda and we spent the morning having breakfast there whilst enjoying the sun! The flat itself has been recently renovated, is very clean, and so quiet, and had everything we needed! Carlos was extremely helpful and recommended a variety of places where to grab a bite to eat and have a drink, he really was a superhost! He was also always very responsive to any questions that we had. I would definitely recommend staying in Carlos' apartment if you are visiting Seville!
