Mercedes was very welcoming from the minute we got there. She recommended and showed us many places to visit and eat and had great knowledge of the area. The place was very beautiful and had a balcony overlooking the square (a lovely place to eat the breakfast food she provides). All in all a the place is in a great location with plenty of places within walking distance, as well as further places which are easily reachable via the metro system (would recommend a travel card, definitely). Mercedes was a very pleasant host who allowed as much privacy as wanted, but was also great for a good chat (not to mention the drinks she made each night!).
P.S. Her dog Frankie is lovely
