I stayed here in 2022 for a few months (long-term stay) and it was great. Jose and Ja-Rei are great hosts and were very responsive and helpful whenever I needed something. The apartment is pretty spacious - there is a kitchen with dishwasher, pot and pan, basic utensils, microwave, etc. + desk + couch + tv, and then a separate bedroom + bathroom. The separation was nicer than a studio would've been. It is definitely large enough for 1 person - this can easily house 2 and also 3 if one person can sleep on the couch (it folds out). It's clean and it pretty much looks exactly as pictured.
The location itself is nice. I was unfamiliar with DC but the apartment itself is in a pretty residential and quiet spot - I never felt unsafe. It also very close to H street, a more crowded street which has a lot of restaurants and bars, a Whole Foods ~9 mins walk away, and a Giant grocery ~12 mins away (I also recommend Jacob's Coffehouse close by for bagels + coffee). It is not the swankiest part of DC, but it is also a perfectly safe and serviceable place to live and an easy commute to other commonly visited parts of DC. Just use common sense if you are out too late on H St. and you will be fine. The X2 bus and 90/92 bus stops are close by - DC buses aren't the most reliable and timely in my experience but that is a reality regardless of where you live. The closest metro stop and Trader Joe's is ~20 min walk away.
One thing to note is that this is a basement apartment, so use the provided dehumidifier often to avoid dampness and mustiness, especially in the bathroom. It is completely private and separate from the upstairs, with its own entrance.
I highly recommend staying here, short-term or long-term! It is as promised in the description, and Jose and Ja-Rei are great about checking-in and making sure everything is alright with the stay.
