The hosts, Elisa and Miguel, are extremely nice and helpful with everything. We had some special requests during our stay and they were always willing to get out of their way to help.
Breakfast at their cafe is very nice and pleasant, and the service is extremely kind and friendly.
The apartment is clean, well-organized, albeit a bit noisy at night, especially on weekends (the location is superb, in the centre of town, so I guess that's a price to pay).
