"The check-in process was ok as we had the opportunity to do most of it in advance. We had a problem getting extra keycards at the check-in point but this was quickly resolved at the guest help desk.
The room was spacious, really comfortable bed, very quiet. Good coffee machine and decent small fridge. Great shower and plenty of clean towels.
We didn’t have breakfast so can’t comment on that; similarly we didn’t eat in the restaurant. The bar was nice with friendly staff, and the onsite 24h self service shop was very handy, especially as we arrived late at night.
The location was perfect for us with buses just outside, and the U1/U2/U3/U4 just 5 minutes walk away at Nollendorfplatz. It’s 10-15 minutes walk from the zoo. You can walk through the Tiergarten to Brandenburg Gate in 20-30 minutes.
There’s a Netto around the corner for stocking up the fridge and getting breakfast items/snacks.
Some small negatives:
Big TV with soundbar, but, WiFi was poor and extremely unstable. There was no ability to connect to the TV via HDMI or airplay which is pretty poor for a 4 star hotel. Almost all the channels were German so not much use holidaying from abroad with limited German.
Weirdly, with 3 of us in the room there were only 2 cups and 2 glasses.
Although the beds were really comfortable, the pillows were awful, but we were so tired from all the sightseeing, it didn’t really matter!"
