This is 3.5 out of 5, but closer to 3, than 4.
Cheerful…read morefriendly service is a big plus, and so was a location very convenient to a train station. Services in the bar and restaurant were exceeding expectations. The price was fairly reasonable too.
Enjoyed the sort of small courtyard for little wine and chat with F&F in the evening. Now, some negatives. Rooms were well sized and spacious, quite clean too, but old and require updating. The main issue is antiquated A/C system that doesn't work properly. This is not true A/C, more like fan that provides air flow, but doesn't really refrigerate an air inside the room. Interesting: we has exactly the same issue in June in Bologna, Italy where we stayed in June in Mercure. Also, it is busy location, so it was noisy in the mornings for light sleepers, like myself. We had to open windows just to sleep, and the morning noise woke me up. Finally, it is not a great area of Munich, at least on one side the neighborhood is a bit sketchy. Not horrible, bit still. If you walk in the opposite direction, it is convenient and easy walk to the center.
