Svetan is a warm and welcoming host and was very accommodating when my arrival time kept changing. The apartment is bright and clean and has the warmth of a real home (which it is, Svetan and another person who was away when I visited actually live there).
The room is a good size and the bed (and especially a particularly firm pillow!) is very comfortable. The room faces onto the street but with windows closed the noise is minimal. However it is quite bright, so if you ned a dark room to sleep, it's worth bringing a sleep mask.
The location is terrific, literally 90 seconds from an Elizabeth line station, just two (longish) stops to Liverpool street. And there are also buses practically on the doorstep.
This is a real home lived in full time by real people who just rent out their spare bedroom on AirBnB, so you are not displacing the local population by renting this space, which is very important to me as so many cities get hollowed-out by short-term lets.
In short, I would very much recommend Svetan's place and will definitely hope it's free the next time I visit London myself.
