Mercedes’ place is great and I loved the decor. Mercedes was prompt with communication and even through she was out of town for my stay, her friend took great care of us! He even gave suggestions for grocery store, dinner, etc... The only issue I had at all was that there is only air conditioning in 1 bedroom and it was unseasonably hot (which no one has control over), so no one’s fault. Otherwise windows open was sufficient on the not as hot days. Very relaxing place, bed comfortable, towels provided. I would stay there again if in Buenos Aires!
