Had a good 4 night stay at the Hyatt. The hotel is right in the centre of Reston town, right by all the shops and restaurants so very convenient. There is also a shuttle every hour from Washington Dulles airport to the hotel which is only 15 minutes away.
My room was huge, comfortable and clean. The bed was very lovely and I slept really well. They also had good sound insulation and I heard almost no noise from neighbours. Breakfast was excellent every morning. There was a really good selection and the service was very friendly. We also ate in the restaurant one night and again the food was really good.
There is also a Panera cafe attached to the hotel which had a good selection of sandwiches, soups, salads, cakes and coffees which was a good alternative.
I would have given the hotel 4 stars, but have marked down based on there cancellation policy. I had originally booked the hotel for 5 nights but needed to reduce this to 4 nights. The only way to do this was to cancel the original booking and then rebook at a much higher rate. Not impressed.
