Excellent quality, stylish en-suite room, 5 minutes to South Kensington tube. Easy and clear check-in, helpful online chat service, a very comfortable and stress-free stay.
Only downside was that this room was not the one I had initially booked, I had booked a room with a large window in a different part of Kensington but was informed at the last minute (day before arrival) that room was in a building that was not finished (I imagine they meant in terms of refurbishment. Surely this could have been made clear earlier, or the property should not have been listed in the first place. The room I stayed in was thankfully very nice, and Sonder were apologetic for the confusion, but I would recommend this is looked into so the same mistake is not replicated. I trust fully it was a one off and this did not spoil my stay thankfully.
Overall a very pleasant stay, I would recommend Sonder and stay with them again.
