@HappyFace2018 We’ve stayed at the Fairview Marriott when we visit our dtr at GWU and really like its secluded location (it’s in a wooded suburban office park). It takes about 20 minutes to drive to campus. We park in the garage near the Law School - $23/day for a week day, $12/day on Saturdays and on Sundays we find free street parking. We just keep the car parked and walk everywhere.
My neighbor, whose daughter also attends GW, uses Priceline and has gotten some AMAZING deals hotel deals in the city, such as $80/night at the Fairmont. She also uses the Parking Panda app to find parking, because hotels in town charge so much for parking.
For those of you traveling with family, I suggest the Residence Inn Fairfax Merrifield (also in Falls Church). The prices are reasonable, breakfast is included, and you’ve got a full kitchen in the room. This location is also ~22 minutes from campus.
