Hi, Fahim. Thank you for the review. The internet is working fine. As explained to you, it was likely an issue with the service provider. I purchased a mobile hotspot and delivered it to you immediately as an alternative before the wifi was resolved. I also offered some compensation for this. The mattress isn't thin and is far in comparison to sleeping on the floor. Regarding the walls, unfortunately, I have little control over this. But noise, if heard at all, is rare. The area is filled with working class people and not known for drugs. It is counted amongst the safest neighborhood in London. I am sorry you feel the need to tarnish my image. Always happy to gain a better understanding from your perspective if you have photos. Thanks again for staying at my flat.
