The information in the listing description is very accurate, and all was as pictured. It's a small flat, but it's centrally located near public transit stops and walking distance from major sights. For my trip, location was more of a priority than the flat's size so this was a good "bang for your buck". I would highly recommend for a solo traveler or a couple, definitely not more than that. There's just enough space to move around, which was fine as I was only really in the flat at night to sleep. It's conveniently located right above some restaurants/bars, but it can be a little loud at night. It didn't bother me and I slept fine, but if you're a very light sleeper perhaps bring some earplugs.
Checking in and out was simple, and Maggie and Lawrence were very communicative throughout the entire process. They provided all the necessary information I needed beforehand, and quickly responded to any questions I had. I would recommend staying with them and would consider rebooking if I return to London.
