When my iPhone suddenly failed to keep a charge, I looked for a nearby repair shop and noticed the LoveFone at 23 Southampton Row had a 5-star rating, so I headed there--and found that the address is actually a re-purposed red phone booth very near the Holborn tube station. The staffer Fouad quickly and accurately diagnosed my defunct battery and replaced it and cleaned up the charging ports while I had a coffee next door. Took my card, instantly sent me an email receipt, and I was good to go; he even recommended a nearby felafel stand for lunch (also very good!). In short, Fouad provided absolutely first-rate professional service for me, so I can recommend his LoveFone location most highly.
