I spent 3 nights at Pepe Y Maru's place, and its beautiful! I was travelling alone, however, the flat is so big that it can accommodate a large group. The flat is spread over 3 floors, and each floor has a bathroom and a bedroom which is very convenient.
The rooftop terrace is the real gem!
Situated in the centre of Seville, all the most famous sites are a less than 10 min walk distance.
Highly recommend.
