This was our first time using airbnb and we were very pleased with the outcome. Even though it was on short notice our hosts were very flexible and communication was an A+. The Pupavac's were SUPER nice and very welcoming.
We took a cab from DCA for like $25 because we had not figured out the metro system yet. The location of the house was not smack in the middle of anything "fun" but the metro was literally a 5 min walk away so you could travel anywhere. There are little eating places nearby as well but you never really go there unless it's for a sandwich or a cup of coffee. Overall we were satisfied with the location given the last minute reservation. It was well located with an easy 25 minute walk to the Capitol and easy acces to the other central parts of Washington. We basically walked to and from the metro. There are a few "sketchy" places surrounding the neighborhood so we didn't venture in that direction. However, the metro takes you everywhere in a short amount of time for much less than a cab. Even if you are staying for 3 days I would recommend getting the monthly pass because the fares to add up depending on how much you want to sightsee.
Our room/bathroom were fine. Everything is exactly as they are in the photos. We had everything we needed to crash since we weren't home for most of the time. There was another couple staying in the room next to us and we saw them once the entire time we were there! The house is always cool and it was nice having an air conditioner in the room. You get used to the humm of it...it's not that bad. The stairs are kind of squeaky so I always felt a tad guilty coming home late like sneaking in but oh well... :)
It was definitely different staying in a stranger's home but you feel like the Pupavac's have been lifetime friends. I would definitely recommend Heather and Vassa's home to anyone. We had a great time in DC!
