All in all, a fine place to stay. In a busy neighborhood, but the street is quiet. If you're a light sleeper, this is the place for you.
The terrace is also lovely. Nice sun in the afternoons. This was another reason we chose it, and weren't disappointed.
The description is accurate. The place is well-maintened, clean and in fine shape.
Probably max for four people (we were a family of 3).
Yes, stairs to the apartment and from the first floor to the second floor. So, not for those who are challanged by movement!
Like many places in Spain, it's likely more cozy in warmer months. Heating (air pump) was adequate, but never cozy. This is not particular to this place. But a few rugs and carpets on the floors would make the place more comfortable in cold months.
Kitchen has all the appliances you need, but the dishes and cutlery are bare minimum.
The "basic essentials" in the kitchen (oil, salt, pepper) are very bare. Be prepared to buy unless the hosts stock up better.
