The apartment is absolutely great: spacious, spotless clean, very comfy beds, nice bathroom and everything you need can be found in the kitchen. It was even possible to prepare small meals which was very convenient for us after a long day of sightseeing. It was a plus to have parking passes and metro cards waiting for us.
Check- in and out was no problem and communication with Meseret very quick.
To sum it up: a very very nice stay in Washington!
