My travel buddy and I really appreciated everything about how we were greeted and welcomed to DC!
Our host had let me know he wouldn't be available for our stay, so some of his family (and their two lovely children) were our contact at the residence - we had several, brief and delightful conversations.
Our lodging requirements were for two beds - so the fold out couch worked just fine for us. The weather during our 5 day visit was mild and we never had to resort to using the 'new' AC/Heater unit. The ceiling fan worked just fine for us.
We'd wanted to stay near downtown, the Mall/Capital and Georgetown - so the neighborhood in Dupont Circle fit the bill perfectly. Though we'd initially planned to use the Metro-Bus transit system to get around - we found ourselves Uber-ing everywhere. The stay location, relative distance to what we wanted to do and price convenience was a game changer...
Regardless of accommodating the need for two beds I'd recommend Tony's space in a heartbeat.
