I stayed at this property for 5 night in early February.

Had a 6th floor room, facing courtyard, very quiet. Windows that open too---combats the inaccurate heating system.

Beware that there is major construction going on outside two sides of the hotel -- expansion of the Berlin subway, and building a new station right at Unter der Linden. Not disclosed on their website.

I found fault with the very uncomfortable, and springy, bouncy mattress. The bed linens were standard Heavenly bed type, but the beds were not.

I reviewed this on the Westin website and they responded by saying that the mattress was a Heavenly bed. I disagree completely.

I stay at Westin hotels more than 3 weeks a year, and know what to expect. The beds here are not "heavenly".
