Just returned from a week at the Adina... made our time in Berlin very easy. Central to everything we wanted, we never travelled west of the Brandenburg Tor, and within easy reach of the U bahn if you did need to...
We walked a lot...possibly too much for our aging limbs, but it was lovely to be able to come back, put your feet up for an hour or so, and then head out again.
Plenty of cafe's/bakeries within 10 min walk for simple breakfast...restaurants for evening meals perhaps not as many as elsewhere, but 5 nights out of seven we ate within walking distance.
We had a room on level 5 looking into the courtyard, very quiet and filled with sunshine each morning.
Having everything in the room, including washing machine/dryer (not used) and all the kitchen facilities meant we could easily have eaten at home...and there's a Lidl just up the road.
Pool was a nice way to wake up in the morning, though it only needs four people in it to make it a little crowded! ...and the changing rooms get very wet on the floor.
Staff all very friendly, especially Aye who had to ride up and down in the lift with us a few times due to key problems on the first day.
Only negative... bar was closed Saturday and Sunday evening with no warnings.
