Maxim

Address: Karl-Liebknecht-Straße, 14, Berlin. A quick check on the map can help confirm the entrance and the easiest approach.

Looks like they're open every day, so you don't need to worry about timing your visit around a closed day.

According to available data, this is a cafe. Usually a better fit for coffee, desserts, short meetups, or getting a bit of work done at a table.

Smoking is only allowed outside. Inside stays clear — which is the norm most people expect these days.

Floor: 0. Useful to know in advance, especially in buildings with limited lift access.
