Apartment (1), Host (2) and Location (3) are pretty nice.
1) In the Apartment we only had minor issues. a) Kitchen: okay equipement; there's only 1 big and 1 small cup; the kitchen knife is dull; no salt or oil. b) Internet: the signal is not stable and sometimes it is not fast enough to stream e.g. netflix, but Egle is quick to take care of issues. c) Bathroom: the shower is hot, but it is very small, the waterpressure of the sink's tab is weak and the bath was not spotless clean.
2) Egle and her team are very responsive and will do their best to cater to your needs.
3) In walking distance from the apartment you can find good grocery stores(e.g. COTO), cafés (e.g. flores poreña), and bars; also tube and bus stations are in walking distance. The neighborhood is calm, clean, nice and humble. It is actually also possible to walk to the districts recoleta, palermo and san telmo (about 1h one way).
