Susan is a gracious and responsive host - she sent informative welcoming messages and kept in regular contact to make sure we were happy with our stay, without in any way being intrusive. She is just lovely. The Green Retreat is an oasis in a smart area of DC, with plenty of good local bars and restaurants. It is a comfortable 15-20 minutes stroll to the main subway networks. It is spotless, well appointed with a pleasant and cosy kitchen / living area. We would heartily recommend the Green Retreat to anyone contemplating a stay in DC.
