Me and my family stayed her during Christmas time. Peter was an excellent host. Always responded quickly to any of my questions or inquiries. Made it one of the easiest check-in/check out experience.
Location is wonderful. Right in the center of London. Around the corner from British museum and 3 minute walk from the tube.
Room can sleep 4 and can very comfortably sleep 3. Water pressure, kitchen, bathroom, and linens are all great quality. It is a few floors up so if you struggle walking up stairs then it may not be the place for you.
For the price I don’t think you can find something better for a small group of friends or family.
