I really enjoyed my stay at Rodolfo's place, it was clean, roomy, and properly stocked with everything needed for a short to middle-term stay. He was also super responsive with any requests I had at the beginning.
The view is gorgeous to wake up to, and to look out at any time of the day. It can be hard to leave the apartment some days, the view and stay is that enjoyable.
Location-wise, you have San Telmo & Puerto Madero waterfront within 5-10 min walking. The immediate area itself is quiet, but there are many food options on the waterfront, supermarkets in Puerto Madero and San Telmo, and cheaper food trucks further out near the Ecological reserve.
Highly recommend, would stay again any time I want to be near the San Telmo, Puerto Madero & La Boca areas of town!
