The communication with sonia was fast and good. The rooms are as described and the for the money good as well. The bus connections to the city are not quite optimal, about 45 minutes, but okay.
The only real criticism is the location: we were explicitly warned by two taxi drivers not to walk around there in the evening, because its not unlikely getting robbed. That didn't happen to us, but we still have made our own experiences.... Especially not the proper location for women and people who do not speak Spanish as their mother tongue.
