We spent 4 nights in October in the apartment which is extremely well located for all the sights and, despite being very central, was quiet. It was spotlessly clean and equipped with everything we needed. Jose Luis provided plenty of useful local information and suggestions which enhanced our visit (in particular how to avoid the queue at the cathedral). He was accommodating with early check in and late checkout, although this will be dependent on the previous/ next guest. If necessary there is a cheap left luggage facility at the tourist information cabin right next to the apartment.
On the less positive side the twin room is quite small but it worked for us. The main thing to be aware of is that the apartment is on the second floor and there isn't a lift so you will have to carry luggage up and down two flights of stairs.
I'd happily stay there again and would recommend this apartment and Jose Luis as a host.
