I have been to the hotel Marcus on 3 different occasions, since friends have stayed there. It is a small hotel (maybe 10 rooms or so), but it's clean and central. Rooms have a private bathroom, even if pretty small, and TV (but what do you need TV for if you don't understand the language???). It is not the hotel Excelsior, of course, but for that price you might be satisfied! I did recommend it to friends in the past, and would do it again.
