Had it not been for a bad experience on our second night, this would have been a good review. The location was perfect for us (going to a Nats game), and the room/house was comfortable. There were some minor, easily fixable issues like exposed drywall/insulation in the bathroom ceiling vents, and a rather shabby looking exterior of the building. Also, be prepared to Lyft/Uber to shopping/restaurants, as the neighborhood is a bit sketchy at night, and the District Wharf is a pretty long walk. There were bigger problems, however, on our second and last night there. A new guest arrived as we were eating dinner and packing before a very early morning flight home. He thought that I was Dennis, and when I told him that we are also guests staying upstairs, he seemed surprised that other people were staying there. Within minutes of him arriving, an entourage of people (8-10, including his girlfriend/wife and a very young baby) arrived, and completely took over the downstairs living room - with loud conversations, partying, music, and TV blaring. I messaged Dennis, and he said he was on his way over. We stayed in our room, and continued packing to stay out of the fray. A while later, Dennis messaged me and said that they would be "leaving in 5 minutes", and he would be back to check in a half hour. That was an uncomfortable half hour for us. I informed Dennis that we were packed, and had called the Hilton Garden Inn near the airport as a back up plan - and that we would leave if this was not resolved. The entourage was still there, and still very loud when Dennis' wife returned. Most of them left while she was there. However, the new guest and his girlfriend/wife and baby were still there. Dennis' wife was cleaning up the mess they had made downstairs when I went down to get our things out of the fridge. She informed me that the new guest(s) upstairs weren't sure if they were leaving or not. I messaged Dennis that we still felt unsafe and uncomfortable, as he could not guarantee the entourage of people wouldn't come back in the middle of the night (since the person who started the problem was still there), and that we felt concerned that he might retaliate against us, since we were the "whistleblowers". Dennis' response was that "he did everything that he could do." I told him that we were leaving for the hotel, and would sort everything out later. We left feeling that he was more concerned about the money to keep his rooms full, than for our safety and comfort. While we were there, we followed all the house rules and were good guests, and we were put in a bad position by a guest that broke all the rules upon arrival - yet we were the ones who were compelled to so we could ensure our own safety and comfort. Dennis refused my request for a one night refund. Adding insult to injury, he had the gall to request an additional $20 cleaning fee - because we left our few dishes from pizza delivery we had when this whole thing started. Feeling unsafe, we weren't going to stick around to do a few dishes! For the record, prior to this, I have never once had to write a negative review for an Airbnb host. But I believe Dennis could have handled this situation better by requiring the person who started the problems to leave, changing the door code, and ensuring the safety and comfort of the guests who had been staying and following the house rules.
