This apartment is wonderful, spacious and close to many restaurants and shops. We were 3 guests but easily could have had space for 4. The hosts were very helpful with good tips, we just had one problem with the toilet and our host came to fix it only a few hours later. This is a very dog friendly neighbourhood and quite safe (we felt very safe in the building) but be mindful of your purse when you are walking around anywhere in Buenos Aires or even sitting in restaurants.
In summary, we highly recommend this airbnb! 5 stars!
P. S. Check out the Palermo Street market on Saturdays and Sundays!
