We loved staying at Petronille's apartment. It was an excellent base for our family visit to London. The location and proximity to the Tube and buses is excellent. The local coffee shops were great. Petronille greeted us personally and made us very welcome. The apartment was beautifully clean and well-equipped. It was a little ironic that the only issue we had from an apartment in Plumber's Row was related to the... plumbing. The boiler unit thingy (that heats the water for the cosy central heating) can be a little noisy and rattly in the room with the double bed. We would happily stay at this lovely apartment again and recommend it to others.
