Sean's studio was small but lovely. It was just the right size for two people, if you're comfortable sharing each other's space a little. Check-in went smoothly; a woman who we assume is Sean's wife showed us in and offered to explain the London public transport system (oyster cards etc) to us, then left us to it.
The place was very clean and well kept, with plenty of towels, cutlery and crockery, and kitchen equipment. The wet room, though it looks small and daunting at first, actually has plenty of space to wash yourself- as long as you remember to not go back in with your socks on when the floor is still wet!
The one thing that bothered us was the lack of an oven, despite the listing stating there'd be one. Also, the microwave was not working when we arrived, but after messaging Sean, he came and fixed it.
Also, the walls (and ceilings) are pretty thin, and we just happened to be unfortunate enough to be staying at the same time as a family with a young baby in the room above, who's crying echoed pretty loudly down to our room. Obviously that's not the host's fault, but if you're a light-sleeper, maybe bring some earplugs just in case.
Overall, the studio is a well-priced and lovely, and Sean is a friendly helpful man who encouraged us to let him know of any issues so he could fix them for us.
