We had a great time staying at Marc's apartment. It was spacious, clean, has all high-end appliances and kitchenware needed to feel like at home. The location is accessible to everything DC has to offer while still being a quiet neighborhood to walk around or go for a run around the Capitol. The Wi-Fi is perfect for remote work, the apartment has 2 extra access points so signal/speed was always good. The mattress was really comfortable was well.
We couldn't have it better on our visit to DC. Marc was a great host and made us feel at home with timely communication and flexibility. I'd definitely check on staying at Marc's apartment if we're back in DC.
