We found the Green Room spacious and very clean, and it's great for people relying on public transport, being only about 150 yards from the Deanwood Metro station on the Orange line. The neighbourhood is a little run down but we didn't feel unsafe. Kevin was a responsive and helpful host.
The place was fairly basic, with utilitarian furnishings and no homey touches. However, it did have everything we needed, including a well set-up kitchen with stove, oven, microwave and fridge-freezer. There was even an iron and ironing board. It lacked a washer and dryer but we found a laundromat a few minutes walk from the Minnesota Ave Metro station (next stop down the line, see below). There were two AC units, for the bedroom and the living room, which kept the temperature quite comfortable even though it was around 85-90 degrees outside.
Local Amenities: There's a small convenience store on the corner of 48th St and Sheriff Rd, four blocks away. It doesn't have much but you can at least get milk and water there. There's a big Safeways supermarket in the East River Park shopping center. This is about 600-700 yards south of the Minnesota Ave Metro station, behind the McDonalds on the corner of Minnesota Ave and Dix St. The CEL laundromat is on Dix St about two or three shops behind the McDonalds, across the road from the Safeways. That area, along Minnesota Ave south of the Minnesota Ave Metro station, also has quite a few cafes and fast food joints if you want to eat out.
Metro Station Closures: All the Metro stations on the Orange line north of Stadium-Armory, including Deanwood and Minnesota Ave, are closed for renovations until 5 September 2022 (Stadium-Armory station is still open). Shuttle buses have replaced the Metro between Stadium-Armory and the closed stations, running about once every 15 minutes. There are Metro staff at the station bus stops, including at Stadium-Armory, to tell you which of the three shuttle bus routes you should take.
All-in-all we would definitely stay at Kevin's Green Room again. I doubt you could find a place as handy to the Metro as this, and it was spacious, clean and had everything we needed.
