We loved staying at the apartment. For the two of us it had everything we wanted as a home away from home: plenty of space, light, all the necessary amenities. Shower could do with a bit more pressure but was fine.
We liked the neighbourhood a lot. For sure, it's not in the city centre but that means that there's a lot to do nearby that's not overrun by tourists. It's also right next door to some fantastic green space which we enjoyed too. The zoo was closed but we did hear lions - we assumed they were safely locked inside the zoo and not prowling the streets.
Very much recommended and we'll look to book again when we return to Washington DC.
