Pauline wasn't the easiest to contact, so at first it was difficult to find out where we were supposed to park and when we could check in etc. We arranged that we could arrive at around 11am and leave the car whilst we headed into the city to explore and arrive later. Pauline said we 'should be fine' to leave it on the road, however when we arrived we found that actually it is a maximum of 2 hours on the road without a permit. We spoke to her roommate who was home at this time, and she said it also should be ok to leave it there as she'd never seen anyone be towed, so we risked it. She turned out to be right, and the car was fine, but if you are worried about it then 100% double check first. These were the only negatives of the trip, everything else was excellent. Pauline and her roommate were really cool and chilled out, we had a great chat with them on one of the nights whilst we cooked our dinner. The room is cosy and wooden, with a very comfy bed - perfect for crashing in after a long day on our feet walking up and down the Mall. The neighbourhood is also great, right next to a school and no more than a 5-10 minute walk to the metro. Would definitely stay here again if we were in DC.
