We just spent one night at Maria Conception's apartment.
We asked at the last moment to arrive 3 hours earlier then planned. Maria kindly accepted without problems.
Her son Xavier was waiting for us and gave us all the explanations we needed.
The apartment is conveniently located about 5 minutes walk from the old city where the night life is taking place; 5 and 20 minutes walk from the 2 train stations, and 40 minutes walk from the bus station.
The room and the private bathroom are comfortable for 2. All necessary accessories are there.
Another room is for rent across the corridor. A lock enables safely closing one's room if another guest is there.
We encountered some difficulty connecting to the Internet the first time.
We had a very good stay.
