You will not find a better AirBnB host. David will be able to help you get around the city, visit the best places, and offer general advice on the city/life in Spain.
His dog and I got along really well. She is very kind and nothing to worry about.
The apartment is perfect if you don't plan to stay inside 24/7. The shared area (kitchen/living room) are beautiful, well equipped and clean. The guest room and bathroom are the same. The bed was especially comfortable with a huge blanket.
The location is north from the main city but if you like nature it's perfect. I spent many evenings by the riverside or going for a run along the river and the park closeby.
For foreigners, please take into account that winters are cold inside in Spain. David has an aircon that can heat, but I would advice house shoes and warm clothing for inside. Outside, it was really worm. I stayed January & February.
