Jimena is a very accommodating and responsive hostess. The flat is Central to everything including subways and bus stations. It's a bit of a hike to Palermo bars at night but taxis are super cheap (~$7-10 USD). The heaters are super effective even for an older (but charming) building. The patio provided great fresh air access day/night. There are 24hr doorman who are observant but friendly. There is also a 24hr liquor store right on the corner for all your needs. Loved this place.
