Judith/Luis were very responsive and friendly – we didn't meet, but their friend let me in without any problems.
The house is basically a glorified hostel, and only in London does a room without its own bathroom at £60 a night count as a good deal. But that notwithstanding, the house served my purposes very well, and I was fortunate to have a top floor, light and spacious, nicely-furnished room – ask for room 8.
