Eliana's place is a San Telmo gem! It is very walkable and so close to restaurants and bars. I felt safe in the area. The unit is just like the pictures - spacious, high ceilings, modern and clean. I especially liked the sun room in the front and sitting there in the mornings :) The bed was firm and good night sleeps- I am a light sleeper and didn't hear any surrounding noise.
The one thing I'd say is that it could use a guidebook with instructions on how to use wifi, AC unit, stove, washer, etc. Other than that, fantastic stay.
