The apartment is great! It is very well designed and stylish, has everything you need if you stay in buenos aires for a couple of days.
Sol y Santiago provided more than the usual airBnB: there is coffee, oil, sugar, shampoo, even a metro card and more! Very thoughtful and perfect for travelers.
It's perfectly located near San telmo center, close to subway and busses and a walk to Puerto Madero. Still it's quiet and we had a good night sleep in the comfortable bed. During the heavy rain we were happy to enjoy some Netflix and super soft towels after a hot shower.
Santiago met us and explained everything, he always replied quickly to all our questions and was very friendly!
We had a wonderful time and can recommend this apparent 100%! It's the best! :)
