Our family stayed at High Meadow in May 2014 for a friend's wedding in Washington Depot. The location is excellent as the house is just 2 miles from stores, restaurants and a classic old town pub (GW Tavern). Richard gave me a nice summary of the town and list of great restaurants to visit. He also provided detailed explanations of the workings of the house and was very responsive, honest and accessible.
The house has great WifFi coverage in the bedrooms and an ATT micro cell for cell service. Unfortunately there is little to no cell coverage in the town of Washington so don't rely on your phone for directions. Print out your directions in advance or take screen shots of your phone before you leave the house.
The outdoor areas are fantastic. It rained so we didn't use the pool much but it is large and very nice. The barn and playroom were great and the kids loved all of the games and sports available (basketball, lacrosse, soccer, golf, hockey, heavy bag, bowling).
Bathrooms have been recently remodeled and are very nice. There are 4 bedrooms upstairs and 2 bedrooms downstairs. I should note that the downstairs bedrooms are cold and not as nice but we didn't need to use them.
There is a BBQ on a nice sunny deck that overlooks a huge meadow. About half of the meadow was mowed and the kids loved looking for fireflies and exploring the grounds.
I highly recommend this house, especially for families, and if I return to Washington I'd love to rent it again.
