Carlos is a nice host and a very kind person. I had a lot of questions about public transport, places to eat out, washing clothes and so on, he was very patient and plenty of recommendations for us. He provided us with a detailed map of Seville and tips on where locals go for tapas and flamenco.
The house is a refurbished apartment, cosy and modern and the rooftop terrace gives you a nice view of the city. It is 15-20 mins walking from the city centre and just a couple of minutes far from the public transport, a cheap solution to get around when outside is a very hot day. The area is very quiet, but plenty of shops and bars open until late.
I highly recommend Carlos's place because of its comfort and because of Carlos's kindness!
