Overall - highly recommend! Francisco's place is beautiful - we loved our time there! It's a 3 story beautiful garden home in Villa Crespo. If you are looking for something local with tons of outdoor space, plants, and natural light -- this is the place. Francisco also took a lot of care with the decor and furniture, so it's really well done and unique. The building is a little older, so that comes with some quirks (like old shower heads/water pressure, no dishwasher, no laundry etc); but we would happily trade some of those conveniences for a really unique stay. And there are easy, cheap laundry places close by that have it back to you in 24hr.
Francisco was extremely communicative and helpful during our stay there. Any small or big question, he was happy to help us out.
The location is perfect -- you are in Villa Crespo, which is full of great restaurants, bars, cafes, and shopping; but altogether still more tranquil and relaxing than Palermo Viejo. The house is in the back off the street, so it's pretty quiet back there. We are glad we didn't stay in Palermo Viejo, which is a little too bustling and commercial.
