Of the 2 places, I AirBnB'ed at in London, Sonder's place was the best. I wished I stayed at Sonder's my entire stay. This is a true 1 bedroom apartment. The location was very close to the subway, about a 5 minute walk.
Boots Pharmacy around the block and it's open late, so if you forget anything, you can always buy it there. There is also a supermarket around the block.
The apartment is in a new building. Key codes are used, so check-in is convenient. There is a elevator in the building, so you don't have to carrying your luggage up the stair case. The apartment is quiet, so you can get a good night sleep. Restaurants are all the next block, there are so many choices to pick from.
The next time I visit London, I am definitely going to book Sonder's apartment.
