I had a great time at Antonio's place! He doesn't speak English but went out of his way to communiate by text, and to translate with our phones when he met me in person at check in. He was a fantastic host and a really nice guy.
The room and bed are small, perfect for a solo traveler. The location is AMAZING and I loved being so close to the Cathedral, the river, and everything else.
One drawback is that the apartment is above a fairly busy bar, so there is some street noise throughout the night. My stay was during a holiday, so there may have been a bit more noise than usual. Something to consider if you need a quiet space.
I would highly recommend this room to anyone traveling solo through Sevilla that wants a place to drop their bags and sleep while exploring a beautiful city.
