We stayed for three night in Rosas appartment.
Apart from the fact, that the appartment was so nice, neat and clean, Rosa herself made the stay worthwhile.
Communication was easy, entering and leaving smooth and helped by her presence. Further, she helped with a bunch of things, that she did not really have to, such as tckets to Sagrada Familia, recomending nice restaurants and calling taxis.
I am not aware of the official qualifications are for being a super host, but after more than 25 stays in different places around the world, I must say that Rosa was the best, and I vote for the title SUPERHOST.
