My roommate and I recently moved from Arlington into DC. We used pro 100 movers (http://www.pro100movers.com/) and they were great! We moved from an apartment complex with an elevator and loading dock to a fourth floor condo with no elevator. I think the total ended up a little under 500 (with tip) for two full bedroom sets of furniture, an entire living room set of furniture, a dining set, and at least 30 boxes (maybe more). They did it in one trip. We went over the estimated time, but their overage rate is extremely fair. $500 for that amount of stuff is a steal! We used our own boxes that we gathered from friends etc, but they also offer boxes, as well as packing/unpacking services, though I do not know how much of an additional fee that is. I do recommend scheduling your move for a weekday morning, and being the first move of the day for them. As they can get behind schedule (we made them a few hours behind schedule because of all of our stuff – oops!). All in all, great movers!
