We stayed with Marcela for four nights, and I can very much recommend her place.
We didn't arrive until midnight, but she very kindly waited up for us. The room is nicely decorated with thoughtful little details (such as apples and candy, umbrellas, tissues, etc) and has a very large and comfortable bed. The bathroom is small but there is a nice private dressing room as well with large mirrors. Everything is spotlessly clean.
Marcela made tasty breakfasts adapted to our taste, and was always ready to prepare it for an hour that suited us.
We got a lot of useful tips about restaurants and places to visit, and when we tried some of them they were indeed very well-chosen.
The area is safe and not touristy at all, and there is a lovely park across the road which is great for strolling in. A small supermarket is situated only 50 meters away.
All in all, this was a great place for our stay, and we are so happy we chose Marcela as our hostess.
