My stay at Carlos place was very pleasant.
I had my nice little room with a desk where i could work in privacy. The flat is very clean and the kitchen has everything you need.
On arrival i was provided with my own set of hygiene products (like shower gel and shampoo etc.), which was nice.
The neighbourhood was rather quiet and the centred location allows you to reach the furthest parts of the city (mountains or the beach) in about 30-45 minutes of walking.
Carlos was away for most of the week so i mostly interacted with his girlfriend/wife and the communication was in spanish only, though it worked and was pleasant as well.
