How to get the best from visiting Dessau and the Bauhaus buildings. I am having problems understanding the layout of the town.
The easiest walk from the center to the Bauhaus is through the underpass at the station. After a few steps you will reach the Seminarplatz place, from where you turn left into Bauhausstrasse. The Meisterhäuser are a little further north (Ebertallee), but are easy to find too. The easiest thing might be to stay in the hotel in the Ebert-Allee (Sieben Säulen, nothing special, but I thought it was ok).
BTW. Dessau has a surprisingly good opera house: https://anhaltisches-theater.de/ .
The nearby Gartenreich ("Garden Kingdom", an UNESCO world heritage site) is worth a visit too.
In addition on the website of the Dessau tourist information office you'll find a city plan indicating the various Bauhaus sites.
