Staying at Andrea's was kind of staying at my friends'.
I booked her place because the location was perfect for me (I was on a business trip), but honestly, I'll do it again, even if I don't need to be around Palermo. The amount of green in that area makes me want to stay in Buenos Aires for a couple more weeks, and just explore...
The place is lovely, full of history, histories and Andrea's collages :)
If you are planning to go to Buenos Aires, you will love this place, trust my word.
