We had a good experience staying at Alex's "nest-in-church". Quarky indeed but well designed, full of light and quite comfortable. The neighbourhood is quuite but has all you need close by, if you don't seek the normal touristic places. We shopped at the nearby Tesco, bought a book at Highgate bookshop and and had good local food and beer at the few nearby pubs. Buses next door, tube not too far. The experience has certainly been positive. 100% recommended.
