Escale takes very good care of the residence, and practically every service you could ask for is already available;
- He provides coffee and tea (rather good quality I might add)
- Forget 1 pillow, each room comes with 6 or so
- Washing machine and drier
- shampoo, soap, towels, etc.
- A heater for when the weather gets too cold, and an iron for your clothes
Once you enter the room, he'll have a binder on the bed waiting for you with all the information you could need; nearby retail stores and restaurants, location of the metro station, etc.
Overall, I can recommend his services wholeheartedly; if you need to visit the DC area, this is an excellent place to call home while you're there!
