Everything was as described, the apartment is small and cozy. The kitchen is very nice and you have everything you need for cooking (good pan and pots), the shower and toilets are the same room, but the shower has a strong flow of water, so it's more than ok.
The bedroom is big and you have a lot of space. Also, the bed is nice and comfortable. You got a closet for your clothes, and tv as well.
The wifi is the best I experienced in Argentina so far, very fast and reliable!
Overall, it was a great experience staying here, and I extended 4 days more. Thanks Esteban!
