If Milo would be the standard for Airbnb probably 98% could close their business. If it would be possible to rate more for something exceptional, I would give it 6/5!
This is my personal experience, you might not feel the same, depending the type of person you are. I will explain more so you can make your own decision if this is going to be a good fit for you.
Milo made me feel welcome and part of his family the moment I booked my stay. First I was still staying at another Airbnb in Palermo, but Milo invited me to a house party. The mix between internationals and locals was perfect. I found new friends that I was hanging out with afterwards.
During my stay, we had an Asado (bbq) where his friends (from BA/Argentina) came. This was such an authentic experience: drinking wine, eating delicious food and having interesting talks with locals.
That being said, you will enjoy living here if you are a social person and like to connect with new people.
The apartment is big over two floors, has 3 bedrooms, plus a rooftop. The interior design makes you feel comfortable and it has everything that you have in your own house.
It is situated in the coolest barrio (neighborhood) but a bit outside all the bars and restaurants (5‘ walk) which makes it a calm during the night.
You feel it‘s not just about making money like many other Airbnb host are handling their property but Milo is truly ensuring that you are having the best stay.
