This is a good space for a quick stay - 5 days or less. My sister and I needed to visit the city to see family who live in Harlem. This location was 4 blocks away from family so it was good to just walk there everyday. It's also close to the subway - between the 125th and 135th stations - so we were able to get anywhere in the city rather quickly.
Several restaurants deliver via Uber Eats, which is good for breakfast - I definitely recommend Frenchy's for coffee and croissants, Zaro's for bagels, El Barrista for baked goods and Harlem Blues Cafe for coffee within walking distance. The space is also right around the corner from a grocery store so very easy to get food and water.
The building is unassuming but is not as nice out front as the buildings around it. We arrived in daytime and were greeted by someone who I don't think was HB. Either way, he showed us around the place and gave us instructions. The space is enough for two people and only two people. The kitchen is tight but has everything you need to make a meal, besides the ingredients to cook. We did have to buy wash cloths and hand towels. There were only 3 spoons, 1 fork and a knife for eating, so we relied on plastic utensils that we got from my family as well as napkins as there were no paper towels or dish towels. There's a french press for coffee, but we just ordered it with our breakfast each day or went around the corner.
It was cold while we were in town so we used the heater, which thankfully did what it needed to do. There is no TV, but there is Wifi so be prepared to stream on your devices. I would stay here again for another quick trip if I had to.
