This place is a jewel in a rockin' awesome neighborhood! We were there at a hot time of year (Christmas and New Year's) and the air conditioning units were fantastic. The place is adorable, with all the amenities we needed. It is located away from the main street (you go through the front door and down a little passage - this is common house construction in B.A.) which made it incredibly quiet - no street noise for the first time ever of my many travels to Buenos Aires!
Our host Ale was extremely responsive to our questions, and got us information about check in ahead of time so we felt very confident about where to go and what to do, and the check in and check out process went very smoothly. She left a map, a reloadable subway/bus card, and several booklets of city information in the living room, and water bottles and snacks in the kitchen.
The neighborhood is called "Palermo SoHo", and has block after block of beer gardens, restaurants of all kinds and levels of fanciness, and endless shops. Also, we visited the ice cream place on the corner steps away from this apartment almost daily!
We got around B.A. mostly by catching a taxi, which was incredibly easy from this apartment. We also walked 5 blocks to Avenida Santa Fe, where we could catch the subway or a bus. (My cousin also tipped us off to the Cafe del Botanico at Santa Fe 3799 for the best pastries we had for breakfast during our stay!)
We had a fantastic stay in Buenos Aires, and this well-located and lovely apartment was a great home base. We will look for this property again when we go back soon!
