Found this hotel via google search as I wanted hotel near Dulles airport. What a find!! I had a car so staying away from city centre was an option, that said, the hotel is visible from the motorway and not hard to find. For the price this is the best hotel I have ever stayed in. And I have travelled around the world staying in many 4 and 5 star hotels. The service is impeccable including front reception being quick with every request and super efficient. Not really warm, fuzzy but so knowledgable about the area and basically anything you want. They extended my checkout time to 4pm when my flight was delayed-- no charge. They have a terrific breakfast and bar area and food from menu until 11pm. Full size room fridge, large spacious and tastefully decorated. I could go on and on about this place, fitness room, laundry, gorgeous property and sparkling clean. Too good to be true. Would come again if in the area.

A nice hotel, in terms of the rooms (they are actually suites more than rooms).

Only problem is, that this is sort of the middle of nowhere, unless you have a vehicle. No dining options within walking distance, except for a petrol station, and a Burger King next to it. However, to walk there, one needs to cross a busy highway with no pedestrian crossing obvious.

In close vicinity to Washington Dulles airport with regular shuttles. These take about 12 minutes in light traffic, and probably 15-20 at other times.

On-site restaurant has limited menu, though the hotel provides an on-site mini shop that has some basic drinks, snacks and microwaveable food. The rooms have microwaves.

Internet access is free for speeds up to 384kbps and higher speeds come at a cost. The low speed option works well for most things and I did not have a need to subscribe to the paid option.

To get anywhere, other than calling a taxi, get on the shuttle to the airport, from where you have multiple options.

Hotel Sierra is possibly the nicest "extended stay" in which I have ever stayed. I was tempted to whip out my camera in the lobby because the feel is so nice. The lobby is modern, but warm in taupes and brown wood. The hotel is huge, but the front desk is small and efficient in the quiet lobby.

The pictures I took of the room speak for themselves. At first, I thought I was the first person to stay in my room. A few things to notice: better-than-averagely stocked kitchen, kitchen table is counter height with a comfy seat, rain showerhead, outlets abound, plenty of light for a variety of tasks, and the living room flat screen is mounted so it can be rotated to be seen in the kitchen.

For an airport layover, this hotel is over the top!! Everyone I came into contact with was so helpful and nice. The rooms are incredible - with very comfy beds and a sea of fluffy pillows! The TV was great, the music upon entering so welcome. I used the pool and the fitness center, ate dinner and breakfast and could have stayed for a week! I highly recommend this hotel, not only for a layover stay - but for a retreat!!
