Felicias place is the perfect base for your DC holiday. We had a wonderful time walking around DC from her apartment. It's about a 30min amble down to the White House and maybe 45mins to the national mall with all the museums. There is also a metro nearby but the weather was so good when we visited that we walked everywhere.
Felicias apartment is all well situated for any budding tri-athletes interested in visiting the city. There is a public pool at the end of the road, a soul cycle within 10mins walk, a a 'vida fitness' gym which does pay as you go membership and there is a lovely run from the apartment to Rock Creek.
Being situated near Adams Morgan gives you a wealth of restaurants right at your doorstep as well.
Honestly, couldn't recommend this apartment enough!
