I stayed at the Residence Inn in Fairfax City for a couple of one week stays and also for a month while waiting to move into my permanent residence. This is a beautiful new hotel super convenient to everything. While the hotel and rooms are wonderful what shines even more are the staff who consistently went above and beyond any hotel I've ever stayed at. Big thanks to Nashan, Monyinette, and for making my move to Virginia the best it could possibly be.
Oddly enough I prefer the studio rooms to the 1 bedrooms which are on the ends of the building. Also wifi is better the more towards the center of the building. Otherwise this is a great hotel, can't recommend it enough!
