The apartment is on the top floor of the building, so I wouldn't recommend it for elderly or people with lots of luggage. Location is great, it is walkable to Chancery Lane and Holborn tube stations, and a few bus stops away from Kings Cross & St Pancras. There are plenty of great coffee and food options nearby. There is also a food co-op around the corner. When we first checked in we were a little worried about the traffic noise, but around 11pm the traffic dies down and it was quiet enough for a good night's rest. Checking in was a breeze because of the receptionist. The wifi was stable enough, and the living/dining/main bedroom were all a comfortable size for 3 adults. The second bedroom was very small (wouldn't recommend it for 2 people even though it is a double bed), as was the bathroom, but it wasn't much of an issue for us.
The water in the shower, however, was quite a problem because it would only give 10 seconds of hot water before going cold, and we had to switch the water off and on again to get another 10 seconds of hot water. Based on previous reviews by other people, it seems like this hot water problem has been around for some time. It was quite frustrating not to have a nice hot shower after a long cold day! On our second day, when we got back to the apartment, there was also a distinct odor which was rather unpleasant, but that went away after a few hours. The smell didn't return after that, so maybe it was a one-off.
Overall, the apartment would be good if the water issue is sorted out!
