At least once or twice a year I typically end up staying in Rosslyn. So far, I've always stayed at the Residence Inn and I've always enjoyed it. I was wondering if anyone that had stayed at both might list some pros & cons.
I've got another 2 week trip coming up next month. Currently, I booked a week at each so I can see for myself, but I might change if someone has a compelling reason one way or the other.
