Lucy's house in/near San Telmo was the perfect stay. We were 12 students on spring holiday and we stayed at the Charming art house for 5 nights. We cannot say anything negative about the place! The pictures do not do the house justice as it is a picturesque garden getaway in the middle of the city. We were within walking distance to San Telmo and the ports as well as many restaurants (Aramburu Bis was a great choice), grocery stores and a lovely panaderia called 'look' with fantastic empanadas.
The house was cleaned everyday by Marta who was great to have around and Lucy was always available when we had questions or concerns.
Lucy is extremely hospitable and I would definitely stay here again.
