The two roomtypes with club access are both standard East wing superior rooms on the 7th floor. The more expensive has a view over the Tiergarten. There are also club deluxe rooms which are on the 8th floor where the lounge is, to book these you have to call the hotel but expect to pay €300 a night. Otherwise book a Westwing deluxe room and pay for lounge access on check in, I prefer them to the club deluxe and to the junior suites.
