Eric was out of town so we were welcomed by his friend Fraser, who also is an Air BnB host. Fraser was very helpful and made sure the toilet was fixed after it broke. The apartment has a great view and lots of space. It's very clean and we had some yummy Nutella and bread, as well as butter and honey waiting for us (and wine). The bed is very comfy.
The noises from outside can get pretty loud (traffic mostly--sirens), so if you are a light sleeper bring earplugs. This did not bother us however. The apartment is a 5 minute walk from the Baker Street subway station, with easy access to four different lines.
Make sure you check out nearby Regents' Park.
