Very good memory there!
Mr. John is a nice man,if you want to get some suggestions about London,just ask him.
About location:The underground stations(Bayswater and Queensway) are nearby,i.e,you can go nearly everywhere in London by underground.Shops and restaurants are open until midnight,very convenient.
About equipment:The toilet is a little bit small for fat guy like me:),but it does not matter a lot.The heating will not work everyday unless the temperature is under a predicted value.
