Superb host :) Valentina was really helpful both prior and trough out our stay. The apartment is charming and in a super convenient location - further from the hustle of tourists but very close to San Marcos, and water bus services, plus there is loads of lovely local cafes.
Just a heads up, if you are traveling with a bigger suitcase - keep in mind that it is an old building, so the stairs are steep and narrow :)
