We were only on London for 16 hours so max and billies place worked well for us for this reason. It’s easy to hop on and off the train and we were able to sight see even with our short time (long layover) there. The app for unlocking the door worked okay for us. We had some wifi trouble since we’re from the states we didn’t have service but we were able to get in fine. Idk why but we had a lot of trouble closing the door and having it lock behind us. When we closed it one way it wouldn’t lock. And when we closed it the other way the app had blocked us from closing the door which we spent like 45 minutes trying to figure it out (maybe we were just jet lagged) I think everything ended up working out fine but we didn’t have a lot of time and we’re rushed most of our time in London. The place is okay but looks nicer in pictures but we didn’t spend much time inside so it worked for us. Thank you for hosting us!
