Gary's place is a fantastic place to for a single person or a couple. The flat is exactly as pictured. The place is clean, the bed is comfortable, the kitchen is fully stocked, WiFi works great. Everything you need to have a comfortable home base for a trip to London.
My wife and I stayed here for 5 nights and we had no complaints or issue. The only negative is the shower is a little bit on the smaller side but that's not a huge deal.
Also be advised that daily trips on the rail to London do add up but that would be the case no matter where you stayed.
We would highly recommend this place to anyone traveling solo or a couple.
