The place is clean but if you are picky about your bed sheets, bring your own. The bathroom is shared but clean. The shower is a little low so if you are tall, you'll have a bit of a rough time. We travelled relatively light but walking from the railway station to this address was a bit of a challenge (too close for any UBER or taxi to pick you up). If you are planning on a touristy kind of trip, I would look for a place closer to downtown London or the attractions you are planning to visit or closer to an underground station since the underground runs faster and more frequent than the railway.
Other than that, it was a nice space to rest and get cleaned during our 1 and 1/2 day trip to London.
