Had a wonderful experience staying here for a one month conference in February 2017--five stars!
Firstly, location--the apartment is very convenient to the metro (red line) and also Union Station (a 10 minute walk or 7 minute drive). It's also a 15 minute car ride to Ronald Reagan airport and a 7 minute ride to Union Station, with trains to BWI. H street is a vibrant area with lots of restaurants and several unique and chain grocery stores nearby for every persuasion. There's also a Whole Foods opening this month (mid-March) two short blocks away.
The apartment is brand-new and beautifully equipped with all modern appliances including a gas-range stove and efficient washer and dryer. The apartment is well stocked with spices, cooking utensils, and anything you could want for cooking your own meal. A coffeemaker, french press, and water heater were all provided as well. The shower was something I looked forward to every day as it was fitted with four shower styles! Heaven. Temperature is fully controlled with two heating/AC units (one just above the bed--very toasty!). As you can likely tell from the photos, the apartment is beautiful with unique and fun details. This place was like a home away from home with every detail looked after.
There is plenty of privacy with a separate entrance and code to enter the unit, which was extremely convenient!
Catherine was a great host, and even updated the wifi while I was there to make it even faster--I had no issues with it while there. She was excellent at communication, responded immediately to texts, and gave me a heads up any time there was anything she thought might affect my stay.
I highly recommend Catherine's place and will seek it out again next time I'm in DC!
