I stayed a few nights in July 2019 for business.
The good:
a) The service is great. The owner went out of his way to make us feel welcome. The staff at reception were very helpful and nothing was an issue when I needed something i.e. Iron, water etc
b) Location. There is not much to choose in Leipheim but the location is a bonus as it right next to the Danube river (2 min walk). The walk along the river is beautiful.
The not so good:
I was in Leipheim when it was well above 30 degree Celsius during the day. The rooms have no air conditioning so my room felt like a sauna. I could open the window fully at night so it became very uncomfortable during the evening.
