This was a fantastic place to stay. Very clean, very well maintained. The communication was great. I recommend downloading the app.
If you stay here and you want to site see, you are about a 5-10 minute walk to the Metro station. The walk seemed very safe and through a very cute little district with lots of restaurants. There is also plenty of places you can walk and eat including a grocery store that is about a 5 minute walk.
If you are planning on flying in without any transportation, you can fly into Raegan International airport, take the metro to the station near here and it's not too bad if you travel light with possibly a small roller suitcase and a backpack.
