Gonzalo is a very nice host, he will make sure you feel comfortable in his flat and will be available for any questions you may have !!
The room is equipped with air conditioning which helps a lot when it's getting really hot, and the bed is super comfy, we slept super good !
There is all you need in the bathroom and in the kitchen, and you can watch tv or enjoy the balcony whenever you want.
When you wanna go out there are lots of bus stops and metro station nearby - although you may take into account that Buenos Aires is a huge city so you're going to spend some time in the transports for sure!
I'd surely recommend this airbnb ! Gonzalo is super nice and open to discussion which makes it easier :)
