I spent almost a week here and it was my best visit to London yet! The room is right on Portobello Road, but noise from outside was never an issue; it was so nice to be able to step out and be right in the market. It's conveniently close to 2 tube stations that can get you about anywhere you need to go in London. James is friendly and has great recommendations (especially for book lovers!).
The room is up a steep, narrow staircase so if stairs are challenging keep that in mind- however even with a bulky carry-on sized suitcase, I didn't have any problems. I didn't see any toiletries provided, but I didn't ask either since I had my own already. Towels and bedding are provided and there's lots of storage space in the room if you want to unpack or store your bags. There is another room above this one and the noise from people walking around was at times quite loud, but primarily during the day so it didn't interrupt my sleep. The check in and check out process was so convenient, and James was flexible with my schedules which made the whole process stress-free.
I definitely will visit again and highly recommend this stay! The location just can't be beat & it's such a great home base for exploring London.
