One word is enough; SUPERB.
Geoffrey is great, nice, helpful ... suberb.
The apartment and garden are great, cosy, comfortable ... superb. Even for four persons it was fine.
The neighborhood is great, famous (George Orwell lived around the corner, the famous house of Edward Cullinan in Camden Mews), it is quiet, feels safe (windows open at night, fresh Kentish Town air) ... suberp.
Bus 29 stops around the corner and brings you all the way down to Trafalgar Square. And very close to the first stop "Golders Green Busstation" of the National Express Coach Bus from Stansted airport, it takes an hour from Golders Green to Stansted, so a perfect location.
Next time we like to stay in Geofrey and Vickey's B&B again.
