Ivan is an excellent host! We had a really great time in Buenos Aires and he gave us lots of tips and recommendations about different places to go and activities we could do. He was disposed to answer all of our questions, and was really attentive (thanks for the towels, fruit and wine ;)!!). The apartment is perfect for 4 people. Comfortable, very clean and really well equipped. Bedrooms are big and everything works good. The location... nothing to say, perfect!! in 5 minutes you are literally everywhere (San Telmo itself, Puerto Madero, casa rosada, center, subway stations...) and you have taxis and buses stopping right outside the apartment. Maybe a little bit noisy at night, but nothing that some earplugs can't fix.
Totally recommendable! We would definitely stay here again.
