I loved my stay at Héctor's apartment. First of all, the location is hard to beat - literally steps away from restaurants, coffee houses, kiosks, grocery stores, pharmacy, etc. as well as the subway station and bus stops. Despite being right by the very busy Avenida Santa Fe (this is a plus as you can find pretty much anything you need along this avenue), it is a very quiet apartment, which was perfect for me.
The apartment is also modern, stylish, and very clean. I felt secure in the building and while walking around the general area even at night. Although Héctor was always available via messaging, I mostly interacted with his daughter Belén during my stay. They were both great hosts, and Belén was very helpful and kind and ready to help if I needed help with something.
Thanks for the excellent stay!
