Jose is a great host. He showed my at the map all the touristic attractions worth seeing. The house is pretty nice, it is 15 minutes walk to Comercia Plaza. There is a mini market really close and a restaurant on the ground floor (but its really quiet around 12.00 am). It is 7-8 minutes walk from Santa Apollonia metro station. It is clean, suitable for a group of friends.
What I would prefer is a bigger radiator as this time of year it is a bit cold at night. Also sometimes the wifi signal was really poor.
