Sonder was in a great spot, located within the Statler hotel in Dallas. The rooms were large and clean, and offered all the amenities that a hotel has and more! Sonder provides access to the hotel pool, gym, etc., and gets you 20% off at the hotel restaurants.
The only reason for not giving a 5 star rating is because their onsite staff leaves after 11pm, so if you have any issues or questions there’s no one onsite until the morning. However this would not deter me from booking with them again.
