This location was great for ease of trains and the underground. I will share that when checking in we were told the Mercure was completely booked, and therefore our room was at the connected sister hotel. When attempting to check into the sister location they shared they did not have our booking, causing us to have to wait 30 minutes for the person from Mercure to come back over with the transfer paperwork. The sister hotel was a decent sized room, though not up to the luxury as shown in the images we thought we were booking with. There was a Nespresso maker and tea kettle in the room, but no tea bags or nespresso pods.
