The place is just as described and shown in the pictures. I is small, however had everything we needed. Quite clean and tidy. The balcony was a plus :-).
The hosts were very responsive and friendly. They were proactive in their communication about arrival time, met us at the apartment to give us the key, and gave us clear instructions about check out.
The location is great - super close to some coffee shops, restaurants, and the subway (which gets you to Plaza de Mayo in about 20 min and we used extensively).
I would highly recommend this place and would stay there again!
