My girlfriend and I stayed at Luis and Ricardo's place for two nights and had a lovely stay. Luis couldn't be there when we arrived (we were delayed) but his friend kindly checked us in and showed us the room and many amenities available to us. The room itself was gorgeous, with a high ceiling and a very comfortable bed. The location was great too, within walking distance of both King's Cross and Farringdon train stations. The building is located in a very nice area, on the corner of a quiet square, and there are plenty of restaurants, bars and shops nearby. We would definitely recommend staying here if visiting London.
