Our host Marisa was super acomodating, attentive and welcoming. When i arrived (ahead of the others) she made sure she explained everything to me and also left comprehensive notes. We spent 8nights here.
The apartment was clean, had quite a well equiped kitchen - plenty for any traveler and with more than you will need in it. We were provided with tea, coffee, condiments which were super usufull and much appreciated.
The location is superb - several buses stop infront of the building, the subway is a few blocks away and shops - bakeries, fruit and veggie shops and whatever other ones you may need, are not further than a stroll.
Marisa left us some transport cards that were super usefull too.
Being a super busy city, that never sleeps, Buenos Aires is noisy. If you, like me, are used to absolute silence when you sleep, get some ear-plugs. I was the only one from our groups of three that used them but i found them necesery.
We had a superb stay and i highly recomend this apartment!
