Hotel Monaco in Munich

I've always avoided the area just south of the Hbh. Lots of hotels there, but it's known for rowdy drunks at night. I prefer something in the altstadt.

More importantly, why do you have a car in Munich? The public transportation is excellent. And driving in Munich isn't pleasant at the best of times. Finding parking can be expensive.

I think I would stick with the Motel One Sued. 5 minute walk to the U-Bahn to get into the center city. A bit more car friendly. But then your other spot has a cool looking strip joint and a slot-machine palace right around the corner. Don't know what you'll do with the car however.

If you are going to have a rental car, make sure that the hotel you pick has its own car parking for guests - it isn't automatic. Don't drive in the city of Munich itself, but use public transport. You only want a car if you are going out into the country, and even then many locations have good train links.

When I read your subject line I mouthed "No."

Please see this conversation from the forum before you make a decision.

We just stayed at Hotel Monaco about a week ago and here's our opinion. First, the pluses... It was super close to the Haupbahnhof - a real plus for train travelers. The owner couldn't have been nicer. She gave us such a warm greeting, it felt like she was sharing her home. The room (we booked for 4) was spacious and clean. Breakfast, although an added charge, was good and pleasantly presented.
Now for the minuses... the neighborhood is kind of loud at night. We were on the 4th floor (5 floors up) and kept the windows closed at night, not a big problem in early June. Of course we were there over a weekend and did have a street view. The neighborhood, although some may find uncomfortable, is basic "urban" to me. I felt comfortable. The beds for three of us were real beds and were comfortable. But the "bed" my daughter used as bed number four was a mattress on the floor. Luckily she sleeps on a futon at home and could handle the hard bed, but ask about it if you need a fourth bed. The towels were like sandpaper. They really need to replace them.
Overall, I'd stay here again if it wasn't in the heat of summer. Without A/C, it would be tough at night.

We stayed at this hotel twice in june. the first time we had one triple and one double room; later in june we had just one double room. during both stays, it was relatively warm outside and the rooms never could cool down. we opened windows and operated fans and it was very uncomfortable during the day and really uncomfortable at night. We could not sleep at all. And then when the windows are open, the noise on the street below (yelling, sirens, cars) was pretty disruptive. We have stayed on street areas many times but this is a bit rougher part of town leading down from the train station to this hotel and it seems to be rougher than when we stayed here 3 years ago. The location is superb, given its proximity to the train station as well as Marion Platz and also central munich attactions, but I don't think we will stay here again on our next trip. Walking the gauntlet from the train station (or sometimes that is how it felt) and then dealing with the heat and noise were not worth it. Plus we paid for the breakfast for five of us at 9 euros apiece and breakfast was to last until 10 am. We arrived at 9:20 and there was limited choice and we had to retrieve our own coffee for refills. it definitely was not worth 9 euros. I think they were probably having an off day since everyone else raves about the breakfast but I was disappointed. the owner is terrific and the rooms are clean and great, beds are comfortable, bathroom is nice, but noise/heat/food were drawbacks for us.
