There is no parking available! The owner told us that there was street parking, but all the signs clearly state that residential permits are required in order to park there. The owner said that the permits are rarely checked, and that I'd probably be fine parking on the street, but I wasn't comfortable taking the chance (and saw several meter maids handing out tickets). So we parked in a lot 4 blocks away, for $30 per day.
The space itself is very nice, spacious by city standards, well-kept and clean. There's a washer and dryer too, which is very handy. Be advised that the only bathroom is in the master bedroom. So while it worked fine for our family, it would not be ideal for adults traveling together, as you'd have to walk through someone else's room to use the bathroom.
Logan Circle is a great location, walkable to plenty of restaurants and bars. The nearest metro stop is about 5-6 blocks away, about a 10-15 minute walk.
