The apartment was much better than I expected. It is in a great location, very safe residential area. I walked around late at night without any concerns. There are several nice casual restaurants within a 150 yards of the apartment. Starbucks is a block away. Uber is very very accessible, never waited more than 5 minutes for a pickup and around $10 for UberX (much less with pool) to get to the monuments.
The apartment itself is very nice. Spacious. Spotless. A full kitchen. Washer and dryer. Bedroom separated from the living area. A real one-bedroom apartment, not a studio that has been converted. Very quiet. Towels and linens and kitchens supplies were all ample and good quality. Fridge was clean. Restful location. For the price I consider the apartment an incredibly good value. The HVAC worked well. The WiFi worked well. The TV with cable worked well. Nothing but good things to say.
Great communication with Matthias. Easy check in and check out. I hope he lets me and my wife stay in the apartment when we return to DC in a few months.
