Whenever I'm in London I visit Camden for at least one day. Shops and market are worth the visit, you can find basically whatever you need there and variety of food is huge. That's why I booked this time in Camden so I can visit everything for every day of my stay. Nico's place is just 5 minutes walk to subway station, bus line 88 which can take you directly to Oxford Circus, Piccadilly, Trafalgar square and Big Ben is minute away, there is supermarket in the building next to it, there is at least 10 different restaurants and fast food spots. If you want to cook your food you have everything available in apartment. Only downside was not so comfy sofa bed for sleep. But if you don't need it you have 2BR with big beds.
