We had a fantastic time at Büke's apartment. It is very nice and chic, super clean and very comfortable. We had everything we needed (even used the building's laundry room) and loved the view. The a/c kept us cool during the late summer heat.
Additionally, the apartment is perfectly situated, in a quiet street and a quiet, beautiful neighborhood but still close to lively Dupont Circle, Foggy Bottom and Georgetown. There are several nice restaurants, supermarkets (Whole Foods) and pharmacies closeby. We walked almost everywhere (20 mins to the National Mall, 20 mins to Georgetown), but the metro is also easy to reach.
Last but not least, Büke was always quick to answer and even left us some prosecco and chocolates (and a nice card) for our honeymoon. If we come back to DC, and we probably will since we really loved the city, we will be staying with Büke again.
