This is a superb apartment. Very well located almost opposite the famous central market and an easy walk to everywhere in the old town and El Carmen. The apartment itself is on the 3rd floor with an elevator. Only one apartment per floor, plus double glazing means it is quiet for somewhere on a main street in an active part of town. There are three small balconies with large tri-fold shutter windows. The furnishings and equipment are first class and decoration has more character than in most rentals without being too fussy. The double bed and linens are excellent quality. The main bedroom can be separated from the living area by a shoji screen. The second bedroom is a small separate room with space for a single bed and roll-out 2nd mattress. I'd consider that for a child, but the apartment is a little small to accommodate 3 or 4 adults for more than a few days.
I haven't met the owners but all communication has been very efficient and understanding - especially as Jaime's English writing skills are very good.
Of all the Airbnb and other apartments I have rented over the past two years, this is for me (a single traveller) by far the best.
