A neat little place, I stayed for 3 nights and had a fantastic time, the flat has a fantastic style, and was well equipped.
The self checkin using the lock box was well done, and the view across the city was amazing.
I had a couple of minor issues - the bed was pretty lumpy, and the curtains aren't full-length, so it was a little tricky to get a full night's sleep.
On balance though, I had a fantastic time, and I'd definitely consider Daniel's place again when I'm in London next.
