Positives: Colin's place is in a fantastic location, really close to Tower Bridge. The view over the marina at night is beautiful. The apartment complex is really clean and safe. On a whole it's also really quiet and peaceful. There's a great supermarket literally across the road too. The kitchen has a countertop oven and two hob rings so you can do a bit of cooking if you like. The balcony is also really lovely. Solid WiFi if you need to work from the flat too.
Downsides: the flat does get really warm even with all windows and doors open and fans on. I think this could be the same for all the flats in the complex. Less of an issue in the winter I'd imagine.
The hot water is also super hot so beware or you can scald yourself. Finally, the seating in the lounge isn't particularly comfortable so it's probably more of an issue if you're not going to be out and about.
