I really enjoy staying at Residence Inns when I travel because of the full kitchen and room to spread out a bit. Some are better than others. This one had everything I needed. First, they provide a free shuttle from BWI which saved money and time. Second, they are 1/4 mile (tops) from the Arundel Mills Mall (a huge mall) which gave me a place to shop, go to the movies, and eat. Third, the staff was friendly and knowledgeable. Fourth, they had a separate sitting area in the foyer to just relax in. Fifth, they had a full breakfast complete with a healthy option of turkey Canadian bacon, Sixth, they had the other Residence Inn usuals gym, pool, hot tub, laundry, etc. Seventh, they had a pool table. No one has a pool table! They also had an indoor/outdoor fireplace with seating to warm up and just relax. I'll be back.

The residence has some quite nice mini suites available, that offer separate room/living areas. I liked not having to sit on the bed to watch TV/snack and liked the chaise longue in the living room. The kitchen has full size fridge, 2 hobs, dishwasher, coffee maker, toaster and microwave.
There are also laundry facilities provided FoC, which is really nice of them.
+ a happy hour in the evenings

Depending on where your room is it can get quite noisy from the nearby highway and airport. Triple glazing?

Great thing being so close to the mall, can spend hours there.

My wife & I stayed with the folks at Residence Inn for 11 days in mid-August. The hotel room was clean and neat and the kitchen was outfitted with everything you'd expect. The gym, hot tub and pool were very relaxing. But the best part was the hotel staff....they were very nice and incredibly accommodating. I worked an early morning shift each weekday and the reception made fresh coffee for me. They treated us like we were the only people in the hotel. An added benefit is that the shopping mall and movie theater is right next door...and it is within minutes of BWI airport. I would absolutely stay here again.

We stayed there last night because of not having an electric at the house. A normal Residence Inn if you have stayed there before. Only two complaints. The floors and walls seem very thin. You can hear every door close and every step above you. So when going, ask for a top floor. Also, the room description says a king bed. There is no way in this world that it was a king bed. We have a king bed at home and we do not touch. On this bed, we had to snuggle just to make it through the night. I am thinking it was a queen or even a double. Breakfast was good in the morning and the pool looked nice.
We did not swim in all. All and all a good hotel with a small bed for $199 at the AAA rate.
