Harry's place is the best. We loved our stay.
Great location, short walk to the old sector. Ten minutes to Marienplatz, less to the subway.
Super quiet, no road noise.
Host is awesome.
We did not use the patio because we were out and about every day, but it is excellent.
No elevator (85 steps), but not a problem for us at all.
No markets nearby, but just plan ahead. We did Dahlmyer (world's best specialty market at Marienplatz) twice and loved it.
Wish all stays were this good.
