We spent four nights at Teresa's place. Teresa is a perfect host, always friendly and welcoming. It was no problem for her that we arrived at 11PM. The house actually is a student's home however Teresa hosts all kind of people (business trips, travellers). Our room was totally furnished with a double bed, wardrobe, commode and a table. We even had our own little bathroom. The accomodation was more or less clean. You should know that the room is situated next to the main entrance, so you'll hear when somebody's leaving/coming.
You share the kitchen with the other people living in the house. There's wifi access but sometimes in our room it didn't work at all.
Over all we would recommend Teresa's place to all low-budget travellers.
