I loved staying at Isa’s apartment. It is very conveniently located to the attractions (about a 10-20 minute walk depending on which) but because you have to walk you feel like you are part of a neighborhood. The surrounding area of Triana has some great tapas bars and restaurants, all that you might need.
The room itself is very spacious with a private patio and its own bathroom. I traveled by myself but this is more than enough space and privacy for two people. Isa is also super kind and provided great recommendations to me. Highly recommend!
