Tania's place is great: the location is central and a lot of the attractions can be reached by foot. It's very clean and exactly the right size for a person traveling alone (and would be ok for a couple). Tania and her mother in law were very nice and helpful, and let me store my luggage with them for a few hours after checkout.
The only downside: the apartment's window (and bed) is RIGHT next to the neighbor's door. I woke up every time the neighbor entered and exited the apartment, sometimes in the middle of the night. She also smokes outside her apartment and i had to sleep with the windows closed so the smoke won't get into the apartment.
But overall a very good experience!
