We rented Hugo's apartment for my sister and brother-in-law for a week while they were in town from the US for our wedding (we live in the US but have an apartment near Hugo's in BA) - Very good central Buenos Aires location; close to downtown, bustling neighborhood during the week, quiet later in the evening and weekends. Hugo is an excellent host; very friendly throughout the entirety of the airbnb process from booking to pre-arrival planning, check-in and check-out.
