What an awesome place. My mum and I stayed here for about 18 days in April (we travelled around Argentina a bit during that time). Gustavo's sister and niece greeted me so kindly and he had even left a bottle of wine as a welcome gift.
Gustavo was a great host, always in touch when we needed anything. He even had a safety box installed ahead of our visit to keep valuables.
The apartment is very secure, comfortable and clean (smells amazing!) and had everything we needed- even a TV and DVD player for downtime.

It is also very close to the busy Santa Fe road- including shops, laundry, Palermo subte station, buses, etc. so very convenient for us to get around buenos aires.

This was our first experience with air bnb and I was quite nervous, but really had nothing to worry about. Highly recommend this place for anyone travelling to BA.
