We met Aj outside in front of Camden Town Station as we discussed previously and he took us to the apartment. It really was a 2 minutes walk.
The apartment is right next to a police station so we weren't worried about getting our stuffs stolen.
The apartment really is like the pictures available online, very clean and equipped with TV, Wifi and we had enough space for 5 adults. (2 couples, 1 single) Note that the single person had to sleep on the extra mattress given by Aj.
The apartment is about 5 minutes away from the Camden Market and 2 minutes away from bars which closed around Midnight or 1-2AM for the latest.
Good to know, there is a supermarket open until Midnight nearby.
Finally, Aj was nice enough to let us check out later than we were supposed to.

Overall, the place was exactly how we wanted it, where we wanted it and we enjoyed it!
