What is your idea of a price?

The Vier Jahreszeiten is a great hotel. It's easy walking distance to the Marienplatz. It's not cheap, by any means.

Try http://www.venere.com/germany/munich/ for reference and locations. They have over 200 hotels listed, which you can sort by location, price, etc....

In July, anything from 70 to 90F would be considered within the "norm".
So you really can't tell. Personally, I would get one with a/c.
But many hotels do have a/c, it's actually a pretty basic feature. Just many Munich hotels which seem to be preferred here on this board are in fact more like pensions. Which often do not have a/c.

It WILL BE humid/humid/humid and yes, i definitely would get A/C. BTW, would you stay in a hotel in Munich in WINTER that didn't have heat?

Dukey1 - There are neither hotel rooms nor private houses without heating in Munich, or anywhere in Germany. Heating is not done via the a/c system, though. There are better, cheaper, healthier and more comfortable technologies for heating than that.

Aircondition is really necessary for maximum one or maybe two weeks per year - at least for German standards of comfort, we know how to let fresh air in rooms and stay comfortable in not so extreme summer conditions. One week per year is not enough to justify expensive installations and waste of energy. You might be unlucky and catch that short hot phase. It may be humid, or not. You may just as well catch a rainy period with temperatures below the 20°C mark. Or you may catch a bit of everything. Every year is different, there are no general rules.

If you are used to what we consider "living in a fridge", aircondition may seem necessary to you even in what we consider conditions easily beaarable - in that case you have to book and pay five-star accommodation, I'm afraid.

Thank you folks for your replies. Per your advice I just booked a hotel with AC.

Good choice. Even if weather is cool and you don't need the ac, you'd be rolling the dice if you hand't make that decision

LOL, what a waste of money. If it was needed, people woud have it. Since it's not needed, NOBODY has AC. Greetings from Munich from some who has lived the last half century in Munich without AC and didn't "suffer".
More likly you will want heating.

Where have you been the last two days? Probably not in Munich LOL
Yesterday it was 86F in the afternoon, baking sunshine and high humidity.
Everybody at the office switched on the A/C after lunch.
This morning it's 54F and drizzle. Yikes, I want the heat back.
Most hotels in the city with a certain size (usually bit larger than the cosy small pension-style hotels many tourists prefer) has central heating and central A/C. It's a basic feature. Just as any modern office building got it. Also in cars it has become a basic feature.
Hard to believe, but even in Munich the 21st century has arrived... to some extent LOL
