Alan's spot has literally EVERYTHING you need for a stay in D.C. The Metro station, coffee, great food all in walking distance. The street parking pass is basically a necessity, but that is included as well. The kitchen is well equipped for cooking and dining in, although we didn't end up using it for that. Too much great food in D.C. The metro ride down to the National Mall is super fast.
The space was squeaky clean and stylish. The water pressure was awesome in the shower, very fragrant body-wash/shampoo/conditioner dispenser included. My wife and I are both quite tall and the shower head was actually tall enough! Super rare find. Nice towel warmer and heated floors round out the washroom experience.
The neighborhood is a great central location to check out the city and felt safe enough for a big city like D.C. We never felt uncomfortable or in danger and one of the neighbors was very friendly and greeted us with a Happy Thanksgiving while she swept her stoop.
Washing machine and dryer are tucked away in the bedroom in a closet and it's really nice to have. Do be warned that the washing machine is pretty loud when it's on spin, so don't try to run a load while you are trying to fall asleep.
The only thing that could have been better was the mattress, but a more normal sized person would probably be plenty comfortable. Notice that this didn't bother me enough to deduct a star, just figured I would mention it for anyone else who is larger.
Overall the space is absolutely A+, especially for the awesome rate. Alan was very clear with check in and communication which is super important to us. His instructions and rules left us without any need for clarification, although he was responsive to anything we needed.
