Thank you for your Question. All Rooms have an air conditioner. You can regulate it by yourself up to 5 Degrees. Standard temeprature is about 20 degrees (depends on the weather) so you can regulate it from 15 to 25 degree.
Dear Chall, in front of the hotel is a bus station. You have to take the bus (10-15 minutes) to the train station and than the S2 direction Erding to the center of munich this also takes about 20 minutes. Best regards
