Location: very convenient and safe. 3 U-Bahn stops from Marienplatz, with the Poccistrasse station right in front of the hotel. 20 minutes on foot.
In my room I had a small kitchenette, very convenient for having my breakfast in my room without the trouble to get out. 2 supermarket are very near to get some food.
Room was ample, very clean, bed was comfortable.
My room was on the street side, but still reasonably quiet. Rooms in the back are totally quiet, I know from past experiences.
Bathroom is not very big /but not cramped), but everything was working very well, so size was not an issue. In many hotels the shower has this or that not working well. Here all was good: lot of water, hot, choice between 2 nozzles.
Wi-Fi is very good (stable 40 Mbit/s up and download speeds). Only, it is not encrypted, so you have to rely on your means to secure your connections.
Love this place (I have been here many times in the last 10 years), though next time I will be in München prices have skyrocketed here and I had to find (and I did find) a more affordable place.
