Simon's room is perhaps not very spacious, especially if you are three people, but you can use the kitchen and dining room without limits.
Simon's apartment is perhaps a bit far from the London center, but it is in a charismatic and interesting neighborhood.
Also, Simon is a very nice person and his apartment is clean. And it seems a good option if you travel to London in value for money.
We have been at Simon's house my wife and I and my 14 year old daughter for 8 days.
Thanks Simon!
I wish you the best.
Excellent!
