I stayed at this apartment for one night in the last week of March. It was perfect for my needs as I was just stopping over for one night on my way to a camping trip. Communication was excellent and Arturo greeted me, introduced me to the flat, was very informative about procedures etc. And was very friendly.
The flat was a nice size, very clean and had all necessary amenities, Wi-Fi, kitchen essentials, bathroom facilities which were all 100%
The only cons were that the outside walls that backed onto the narrow streets were not very sound proof and I could hear everything as if it was happening beside me, I think this is quite typical of buildings in the old town and I am a very heavy sleeper so it was no problem for me. Also the flat was quite cold in the evening and I had to wear warm clothes to bed to keep me warm.
Apart from this the flat was perfect and in a very nice traditional setting. I would definitely recommend.
