I recently stayed at the Residence Inn Danbury for a couple of nights while in CT. The room I had was a one-bedroom studio suite. It was a very nice, clean room. The hotel staff was friendly and the free breakfast and dinners weren't bad either. Of course, you could always walk next door or drive around the block to get something else.
The hotel was very quiet mostly with little noises experienced at night. The days I were there the hotel had little vacancy and I still had plenty of peace and quiet in my room.
I would definitely stay here again.
