I stayed for 2 nights this week. I'd originally booked the Mercure Alexanderplatz but that hotel was closed, so they offered me accommodation at the Best Western am Spittlemarkt which is owned by the same company.
Although this hotel was slightly more expensive, they honored my original rate and recognised my Accor status with an upgrade to a Junior Suite.
Check in was very quick and easy, and the reception manager was extremely friendly.
My 6th floor room was very clean, spacious and modern. The bed was comfortable, and there was plenty of storage space and a large desk. Tea/coffee facilities were available, along with a fridge.
The ensuite was large with a separate bath and shower with good water pressure.
The only downside would be the boring, somewhat clinical decor; alot of the space in the room was unused. On the flip side, there was alot of natural light, and whilst my room faced the street it was perfectly quiet at night.
The hotel is well located for exploring the sights of Berlin. U-bahnhof Spittlemarkt is just 2 minutes walk away from where you can catch the U2 and several bus routes. It's about 40 mins by bus and u-bahn from Tegel Airport (though TXL will close in a couple of weeks). You can walk to Alexanderplatz and Unter den Linden in 15 minutes and Checkpoint Charlie & Brander burger Tor are also within walking distance.
There's a really good café opposite the hotel which offers a good breakfast, with a Spanish restaurant and bar next door. The hotel bar is reasonably priced too.
All in all a good choice for a short stay in Berlin. less
