The good things first:
Location, location, location!
Matt’s place is so close to everything, only a few minutes away from all the touristic places.
The communication was excellent and the apartment was quite big for London standards.
A big screen TV with Netflix and a fully equipped kitchen were a plus too.
Things to be aware of:
The bed is comfortable but quite small, the hot water had so low pressure that it was almost impossible to take a proper shower and the neighbor’s (a beer pub) customers were quite loud until late in the night, as one would expect during the weekend.
All in all it was a great place to stay that I highly recommend if you are comfortable with the above mentioned things.
