Marcela's place is in a great central location in Recoleta, steps away from the cemetery, public transport, and plenty of nice restaurants and bars. The apartment itself has everything you need, and it's nice to have a living room as well as a bedroom. Marcela greeted us in person and gave us a thorough tour, and loads of tips of where to eat and drink in the city. She also showed us the laundromat around the corner, which we appreciated! (And is very affordable.) The AC was much appreciated during our first summertime Christmas!! Both before and during the trip whenever we had any questions, Marcela was always available to answer them promptly, and she was flexible about some changes to the booking. We were there over Christmas and the city was very quiet, so we definitely appreciated the Smart TV and Netflix (sometimes the TV disconnects from the wifi but this is easy to fix). We really appreciated the Sube card (public transport card). We had a great stay and would stay again.
A few notes that may be important to some travelers: the apartment *is* small; not a lot of room to spread out. The bathroom is small too, and the way it set up means that it is very awkward to climb out of the bathtub safely (the bathtub is very slippery and the toilet is positioned a few centimeters away from where you have to climb out.)
