Allen's house fit our needs well for a 7 person family visiting Washington DC. The house is located in a wonderful neighborhood with easy access to everything there is to see in the capital. Restaurants and stores are only a few blocks away on Connecticut Ave which was nice to stroll at night. Adams Morgan, another hip neighborhood full of restaurants and bars was only a short walk away. Ideally, we would have liked to see a nicer and cleaner interior given the price of the stay, but we understood the times and peak travel season.
The top floors have wonderful rooms that are spacious and well lit with natural skylights. The A/C was a huge plus given the summer humid heat. Two bedrooms are located in the basement with their own restroom and shower. The basement rooms' beds seems to be older and not as clean as the beds upstairs. The comforter cover smelled a bit of previous guests' sweat and some of the pillows seemed like they should be washed or replaced. Given the in-unit laundry, these were all things we could deal with, but we had a higher expectation given the nightly rate.
Long term street parking doesn't exist in the neighborhood so the back alley fenced parking was a great option. Paying extra for it to the host seemed unusual given the nightly rate for the house, but was understandable.
The host was very responsive to messages during our stay and helped us with A/C control, parking, checking in earlier and checking out later, all with very quick response times. Overall, we had a good stay in Allen's house and would recommend it to others looking for a place for a large group to stay in DC!
