This apartment was great. We'll definitely want to stay here again.
First, great location (it's also a block away from my mother-in-law). Surrounded by restaurants, bakeries, and markets, this is a great location to base yourself out of.
The flat itself is very comfortable. Big tv, comfortable kitchen (though we didn't have any opportunity to cook from it), new bathroom, good air conditioning (we needed it during several hot days!) and a comfy couch. The bed was great too, even though it's a bit too small for us (we're two big guys!).
Cecilia was also great, she was very attentive, open to questions, and made us feel very welcome. This Airbnb was a great experience and will be the first place we check upon our next trip to Buenos Aires.
