My inlaws are going to Berlin in August for 5 nights. They are not able to do a lot of walking, so I want to make sure that they are staying in a good location. They are considering choosing between 2 hotels: the Hotel Palace ( on Budapester Str. nearby Kurfürstendamm) or the Park Inn in Alexanderplatz.
Which location would be better to provide inexpensive/moderately priced meals within a few blocks? Any particular restaurant recommendations that are very close?
