Eduardo's place was pretty conveniently located for the price. It was less than a ten-minute walk from the nearest Metro stop, and I actually walked back to it from the city center a number of times (it wasn't a quick walk, but it was relatively easy, and it was nice to observe the neighborhoods and businesses along the way). There are quite a few shops close by, and a very nice park with great views of the city just a couple of blocks away.
Eduardo was very helpful whenever I had questions. He also speaks English, so it's a great place to stay if you speak English but not much (or any) Spanish. Eduardo set aside a shelf in the refrigerator and kitchen cupboard for me, as well as spaces in the bathroom, which were very helpful. The room was nice, and the bed was firm and comfortable. There is an extra room next door to the room that was available for use, but I ended up not really using it, as I found it was just as convenient to use the desk and space in the room with the bed. But, it was nice to know that it was available if needed. Overall it was a very nice stay.
