Marco is the best host ever, super friendly and accommodating. His penthouse is absolutely amazing! The location is one of the best in DC, with plenty of restaurants and bars. The place is on a quiet area off U street, with the metro station just a few steps away. The two living rooms are fantastic, with plenty of light and open space to work and relax. The rooftop makes it perfect! There was another guest in the house, but the place is so big we rarely run into each other, and I had all the privacy I needed. Everything worked out great. Highly recommended :)
