We had a really nice time at Kieran's. The flat is well located and furnished. If you don't want to cook, you can find a cool pub, recommended by guide du routard. There's also a Mac Donald's around. Shops are also close.
Maybe a bit cold as the heater is programmed a few hours in the morning and then in the evening. It's most of the time enough when you come to London to visit the city. We had checked that the heater would work from 6PM and were looking forward to be warm at home after a long day walking in the cold. We arrived home at 6:30 and the heater was still cold. It finally turned on at 6:40.
Don't worry cause Kieran leaved a note explaining how to stop the program to get warm continuously what we didn't make. I would recommend, when it's really cold outside to stop the heating program.
Also, I couldn't find a hair dryer - I actually did not search neither did I call Kieran. If you really need one, you should ask for it.
