Our stay here was perfect! The loft is exactly like what is on the pictures, it's very bright and very homey. And the location is just awesome - supermarkets, dry cleaner and subte super close, and restaurants/bars are aboundant.
We haven't met Clara, but she was quick and great in responding our questions online. And her sister is very lovely!
The only hickup is that if you want to prepare a proper meal, you have to be inventive as there are few utensils at hand (it's possible :). Otherwise, we highly recommend this place.
