We stayed at Ruben's for a night between our travels and it was a lovely place to stay. He provided breakfast and coffee. The bed was comfortable and the apartment was warm. Unfortunately we didn't stay long enough to take advantage of many of the amenities, but we enjoyed our stay!
For anyone looking to arrive at night from the train station, I would heavily recommend a bus or Uber. We walked the short walk from the station, but it's through some neighborhoods that felt a bit unsafe. Ruben's neighborhood does not feel that way, however the route there was a bit dicey.
I believe the listing says this, but there is a small flight of stairs between the upstairs and the bathroom, just as a note for anyone with mobility issues.
