Staying at Manuel's was a great experience. The flat is clean, spacious and cozy and it's 15 minutes walking distance from the center, which makes it a perfect location if you want to spend some time in Seville. Manuel really is a nice and welcoming person (and also a good english speaker :D). He gaved us some great tips and directions to visit the city and offered us snacks and beer on return. We really enjoyed and had fun on our evening chats and the only regret is that we couldn't stay longer.
I would definitely recommend visiting Manuel if you travel to Seville. He will make your stay even more enjoyable!
Cheers!
