My partner and I stayed at Chema's place only for one night. He's very welcoming and happy to give you suggestions about the city and recommendations for your staying over.
The apartment has a good location, at walking distance from the city centre. It was very clean and comfortable.
Only negative things were that we couldn't find any toilet paper (and the only available roll was almost finished) and it was quite noisy at night, because of some pipes I guess. It felt like having water flooding in the apartment. However it's been a positive staying for us and I would still recommend it.
