We had a great experience staying at the Boss!

Host:
The host was great. They were very responsive to any inquiries and offered to help as able. The person who met us upon arrival gave us a great 101 on the apartment and Buenos Aires that was perfectly detailed yet succinct. She provided a map and marked it with recommendations, described how to use the apartment's phone and answered any and all questions. The host was also willing to be on call at anytime should we have needed a taxi called or reservations made.

Apartment:
The apartment was very secure and clean. We had no issues with the wifi--it worked great! We had four of us staying, and all of us were comfortable.

Location:
While we were initially going to stay in San Telmo, we were happy we stayed in Palermo and the location of the apartment likely had a lot to do with that. It was nice for us to walk to the plazas and local cafes and restaurants (5-15 mins. in any direction). Of note, for steak lovers, key restaurants La Carniceria, Don Julio and La Cabrera are all within walking distance. I would caution that we did do a lot of walking, but we tend to do that when visiting big cities.
