We stayed in Alan's apartment during our whistlestop visit to Washington. The apartment was fantastically well placed. On arrival we dropped bags and walked down to the National Mall, about 25 minutes away. The apartment was very close to a metro stop, but so central is was inexpensive by taxi to any tourist destination.
The apartment itself was very clean and comfortable. There were lots of extras, e.g., coffee/preserves/toiletries/guides, etc etc. with lots of clear instructions on how to get the best out of your stay in both the apartment and the local area.
Alan was very easy to communicate with and very very helpful. He kindly ket us leave our bags for the afternoon of our departure as we had an evening train to catch.
We would definitely stay here again.
