I would highlight a few things I really liked about my stay. :)
First, the single room was very quiet, so I had a nice sleep every night (no noise from the outside people or traffic etc.) + there was air conditioning. Second, it is very close to the city center so I did not have to use the public transport at all. Third, Juan Antonio was communicative and very nice to me. Okay, the appartment is decently old, and there is one shared bathroom for all the guests but it did not bother me or disrupt my stay. :)) Overall, great value for money!!
