The experience, in one word, is 'great'! Heather's home is very close to the nearest metro station (Easter Market Metro), around 9-10 minutes walking distance from her home. The check-in was very smooth, Heather provided clear and straightforward instructions beforehand. The room was very cozy, had a spacious closet and nice beds. She even had a binder in the bedside table containing all the information that you need to get around the city- restaurants, attractions to visit and their contacts. You will find the washroom very clean and packed with basic toiletries.
What I personally liked about the place is that it is very well organized, has a library full of books and tasteful artwork all over the place. You will find it very soothing.
Heather is also a very friendly person (also her dog!) and very knowledgeable about the city. She spent some time with us and it was a delightful experience. She is also very helpful; if you have any queries, she will try her best to provide you with useful information.
I recommend her place and if I visit Washington DC again, I will try to book her house from Airbnb if it is available.
