Mercedes is a welcoming and generous host. She arranged contacts for airport pickup and drop off (a bit cheaper than a taxi), offered coffee and breakfast in the mornings and snacks in the afternoons. She was knowledgeable about the city and helpful with suggestions. She has a large and quiet dog. She has three guest rooms -- all just about big enough for a queen-sized bed. Our room had a private sink/toilet and a little balcony, other rooms had just beds with bathroom in the hall. (We could use that bathroom as well, for showering.) Access to full kitchen. We had nice interactions with the other guests, but were able to maintain our privacy. It's a fifth-floor walkup, so be prepared for exercise. Located in the heart of the old part of town, central to everything. Upside: easy access. Downside: in the midst of Tourist Heaven, so everything is extremely crowded. But the apartment is in the back and quiet enough. All in all a bit rough around the edges, but lively and enjoyable.
