Great place in every sense. The location is suberb: two blocks from the train station, right in front of a great ice cream place and the best fish store in the city, restaurants all over, the best medialunas in the city (Lucio) two blocks away, many bookstores around. Five minutes from Bosques de Palermo, ideal for a morning run.
The place is small, as described: fully equipped. I was there for 20 days so I cooked, used the washing machine. All works perfectly.
Lucila's response was great as well: She was flexible with check in and check out times. When the internet went down in the area, she contacted the company in no time even though it was not a problem related to her apartment (the company fixed it right away).
Overall: ideal apartment for 1 or 2, either for short or longer stays.
