The place is pretty much exactly as advertised. Bartolome responded very quickly to all communications, the place is very centrally located in the old town steps away from the main square, and very clean. Comfortably sleeps 3 people (2 x 1 bedroom, 1 x 1 bedroom).
As many have noted it is at the top of a quite steep set of stairs to the 5th floor, so you'll probably want to plan your day out so you don't keep having to go back to the apartment.
Also while the windows do a great job of shielding you from outside noise (including church/clock bells), the if the apartment above/below you has noisy guests you'll hear them (though they are signs up warning guests to be quiet at night).
