We do a lot of travelling as a family and I find it much easier to stay in an apartment rather than a hotel. It’s often cheaper too and you have washing machine, kitchen etc to use. I have had good success with Airbnb where people can rent out a room or their whole home. I have used them all over the world, often renting from other families so my boys have toys and books to play with. There are a quite few options here in Bielefeld, so very useful if you have friends and family coming and they are looking for a place to stay. Or if you need a place short term.
