I've stayed at this hotel several times over the last few years, and I was quite satisfied. The hotel is located conveniently near a Metro station, and within walking distance from many restaurants, pubs, and coffee shops. The rooms are spacious, and the in house restaurant provides good and healthy food choices for breakfast. The staff has always been friendly. This time however, I noticed a significant improvement in staff attitude. The level of friendliness and cooperation has increased even further. You can see it very clearly when the food services manager walks from table to table during breakfast to ask if the guests are satisfied, and suggests various options for the guests to try. The event coordinator check personally if the participants are happy with the arrangements. Front desk staff remember your name, wish you a productive day, and ask you how your day was upon your return. This is well beyond what one would expect at a mid-level hotel. Clearly, this is a great hotel choice for visitors in Arlington or Washington DC.
