Kofi's place is very well located. The apartment is exactly as shown in the pictures. I would just suggest to get a new mattress (the one in the master bedroom seems to have it's due of mileage) and to install blackout curtains for better sleep.
Last but not least, Kofi is a great guy. Very attentive to my inquiries and was most kind to let us leave the luggage at the apartment as the train was departing on the afternoon.
So, in sum, if you are looking for an easy going apartment in central London, this is the one.
