The place was very old and rundown. I had no idea how narrow and claustrophobic it was. Amenities were severely lacking. To my dismay, there was no kitchen where I could wash up my cutlery. The kettle was extremely filthy. It was also quite hard to sleep at night due to various strange sounds coming from the heater and pipes. You can also hear night trains' screeching brakes from the nearby station. This place is also very near Chelsea FC (Stamford Bridge) Stadium so if you don't like football good luck trying to sleep on a match night. Apart from the person who let me in (whom I assume is the host's son), nobody met or spoke to me, which I found weird but also did not mind.
Despite this, big up to the host for being so understanding and helpful. I feel sorry writing this review but I have to be honest.
Overall, I felt like this room was slightly overpriced, as you can get much better accommodation for around the same price.
