Honest factual review.
UNIT: good for solo travelers. Tiny. Very clean. Location is great. 5 minute walk to Baker Street Tube. NOTE: 73 steps to climb, very very narrow also. I'm a powerlifter, and still not easy to reach the unit with a large suitcase. Very hot and humid in the unit (28.5 Celcius noted during my stay), and in the building. No air circulation at all, important to note for summer stays. Windows open about 3 inches, no air comes in. No AC. Bathroom is great, washer and dryer convenient. Bed is ok, nothing special (pull-out sofa-bed)
HOST: keeping in mind that this is a SUPERHOST....which do charge a premium... very very slow responses (almost always more than 24 hours), or even unresponsive at 2 instances. Inaccurate instructions regarding wifi access (responded 28 hours after my inquiry). Inaccurate information about the bin room which got me yelled at from a neighbor (host says bin room at left of building, but is at the right side). Again, responded more than 24 hours after inquiry. Didn't check if all was ok during stay (which ALL the other superhosts I've stayed with over the years did). So if you're willing to pay extra for a superhost unit who doesn't respond in a timely manner and give inaccurate instructions, I DO recommend this unit. But I wouldn't return personally, as I feel that business wasn't done properly here. Paying a premium means getting premium responses, and it surely didn't happen during my stay here.
