To say Mark is a Superhost is an understatement! He is one of the best hosts we have met in our multiple travels around the world. He was super fast on replies to our texts, and he made special accommodations to our early arrival and our late departure. He was always very friendly and helpful before and throughout our stay. He even touched base with us during our trip to see if we needed anything. Plus, he left laundry detergent in case the one at the apartment was low. You can tell that Mark takes pride in his listing with the amenities he offers, the apartment’s presentation, and his helpful assistance. The apartment itself was super clean and modern. I appreciated it especially since I am a clean freak. There were four of us - myself, my husband, and our two teenage girls. The apartment is big and we fit very comfortably. It is located within walking distance to the metro, restaurants, and Starbucks! We were able to visit all the museums and memorials within 20 minutes (walking and using the Metro). The area is super safe, high-end shops, and security guards walking around the neighborhood. Overall, I highly recommend this accommodation to everybody looking to stay in downtown Washington DC.
