We stayed at Matt's flat for 3 days with 3 of my friends and I. It was a pleasant stay, close to the O2 arena where the even we were all attending was happening which was making thing easier for us a it is only one stop away.
Matt welcome us himself at the flat showing us around and all the details about anything we would need to know. He was available to reach though we've not needed too as he explained everything very well beforehand.
The flat was true to the description and pictures. There was a lot of convenient things to use such as lots of bath towels, a washing machine, even tampons. The real bed was comfortable, my friends found the other matters ok but not perfect.
Also the flat is on the 9th floor and it was ok most of the time when the elevator worked but it happened one night it wasn't and it was difficult taking the suitcases up plus I had a sore knee... fortunately we encountered the neighbor who helped us.
The place is well located around 8 mins far from the tube. There's a lot of convenient stores and a few restaurants next to the flat, even a tore that opens 24/7.
Matt was very welcoming and willing to help us around in London, making himself available and a nice an social person.
In brief we had a good stay. The flat is nicely clean. I recommend Matt's place for a stay in London near the O2 and surroundings.
