Whether you find this apartment satisfactory or not all depends on your expectations. The price was one of the most reasonable in Central London and the location, with its proximity to King's Cross/St. Pancras and bus stops, is excellent for travelling in and around London. With that said, you get what you pay for. The photos look better than the place in person and it has some major flaws.
We were able to check-in an hour early but there was no toilet paper in the apartment when we arrived. No paper products at all: no toilet paper, no paper towels, no tissue. One bath towel per person was provided but no hand towels or floor towel to step on out of the shower. The bathroom only had a handheld shower with nowhere to hang the showerhead. For Americans unused to showering this way, it took a bit of getting used to. No hair dryer.
In the kitchen there is cookware and dinnerware as well as a stove, oven, toaster and kettle. No dishwasher so we washed our dishes every evening but there was nothing to dry our hands on except our bath towels.
The Wi-Fi seemed to go in and out every evening. With no air conditioning it's necessary to open the windows during hot weather but the apartment is located on a very busy street with cars, buses, emergency vehicles and large trucks buzzing by all day and night so it's extremely noisy. It's difficult to hold a conversation in the kitchen/living room with the windows open. Even with ear plugs and the windows closed, it was difficult to sleep at night in the front room. The bedroom is quieter so if you don't have a 3rd person, then the noise will not be as much of a problem.
If the price and location are more important to you than the flaws then you will be happy. Otherwise I would look elsewhere.
