I came to London for my new job and I chose Al's flat for my temporary stay until I could find my own place. I lived there for 40 days I think my opinion is pretty solid:

Al is a really awesome host. He is very chilled and friendly.
He works and travels a lot (so you end up having the flat all for yourself quite often) and sometimes his girlfriend comes with him to the apartment and she is as cool as him. I had some cool conversations with them. They're really good people.

The house itself is even better than what it looks in the picture. The decoration is amazing, both the bathroom and the room are great, the space is really big and cozy so you feel yourself at home pretty quickly.

The apartment is very well placed. It's right next to Shoreditch (one of the coolest regions of London for going out) and to the city (if you're coming for business) but it's still in a slightly calmer region so things are not overpriced. It's close to 2 metro lines so you won't have any issues with transportation. Living in this region is so convenient that I ended up choosing it for my new apartment.

Given how expensive rent is in London, the price of this one a is really good deal. The cost-benefit is amazing.

To sum it up: I can't recommend this enough. I'm really glad that I chose this flat. It exceeded my expectations, no downsides at all. If you're coming to London for whatever reason and this Flat got on your AirBnB radar this is a no-brainer: just go with this one and enjoy your stay.
