The apartment is nice, equipped with everything that you need (except for thrash bag and detergent).
The host is super nice, very responsive and friendly. She really wanted to ensure my stay to be comfortable.
The only downside is the noise from building construction beside and also the soundproof of this building is really bad. But then, this apartment is quite the cheapest I found in Puerto Madero, it was acceptable for my 10 days stay.
