Stayed just one night, from the afternoon to the early morning. It looks nice enough to stay for longer periods as well. My main concern was the proximity to the train station. It was resonably close (around 12-15 mins of walking carrying a heavy backpack).
The room was large and clean. Upon arrival to the station I called Isabela and spoke to a member of her family who spoke good English. She met me together with another man from the family at the appartment 10 mins later, showed me around and left. the house has several rooms and there was one vacant for a friend of mine who showed up with me hoping there would be a room for him as well...
There was a nice little kitchen , and a back yard for smokers, that I didn't get to use. There was a cafe close by, the streets looked safe even at night.
I would happily stay there again.
