Nice location, great responsiveness from host, and very accommodating. Overall, the apartment would have only gotten 3 stars had it not been for the kind host and quick responses.
Two of the bedrooms are separated by doors - not a wall - which means any noise in one room is easily heard in the other. The apartment itself wasn't terribly well provisioned - there were no paper towels, kitchen rags, sponges, and we had 2 total rolls of toilet paper for all 6 people.
The living space is quaint but nice. One quick call out - the street noise can be a bit loud in two of the bedrooms, and since it's Spain the loudest times are between 1AM-4AM. Bring your earplugs and you'll be fine!
