This is one of the best Airbnb experiences we have had. For me, it comes down to three things: the flat, the location and the host. This was an 11 out of 10 on each.
The mews house was great. Very, very quaint. Quite large by London standards with a very large living room. For instance, It has a couch that two adults could lie in at either end and your feet would not touch.). Lots of seating. A good sized kitchen that Is fully equipped with tons of glassware/plate ware, a dishwasher, and a washing machine (no dryer but there is a drying rack that works fine.). Three bedrooms- 2 are really very large (rooms for a desk in each). Two bathrooms- one with a shower/bath, and one with a shower. The entire place is full of light and brights. We had 5 of us for two nights and 4 for 4 nights, and did to feel remotely squished in. Good Wi-Fi throughout. (I should not that to access the flat you have to go up a narrow stairwell, so may not work for people who have mobility challenges.)
The location is fantastic for London. It is on a very quiet mews street. No noise at all. (And for that reason, you should not use this as a party house. It is quiet and meant to be quiet. If you are looking to have a loud party, better to go somewhere else.). It is two blocks from oxford circus so easy tube access to a bunch of different tube lines. Easy 10 min walk to regents park and maybe a 15 walk to Hyde park. Great places to go running. Lots of great restaurants in the neighborhood, and there are several grocery stores within a few blocks.
Finally, the host andreea was great. I have had issues in the past of last minute cancellations , so I worry about this. Andreea could not have been better- great communication on the way in. She was on holiday but had someone available throughout the week. We had a problem with the hot water (these things happen), and she have us so many options, ranging from offering to find us a different place, rent us a hotel nearby to shower, etc- she took it so seriously and made it so easy for us. You can tell a lot about someone when there are problems. I cannot recommend her more highly as a host. I only hope she buys and lists more Airbnb properties.
All in all, I cannot recommend this place more. If I am ever back with my family, this will be my go to place.
