Our host was very kind, met us in person and guided us through everything while giving very good tips on the city.
We speak (a bit) of Spanish which made communicating easier but he gets around with English as well to explain you everything you need to know.
The appartement is clean, spacious (you can easily live with 4 persons) and very well located. It is located in a calm, one-way street just outside the touristic center of the city, but you can easily access everything by foot. This gives you also the benefit of a good night sleep as it can be quite noisy on the streets in the Spanish city centers.
