We decided to take the big oven because we like oven dishes, and if you have a couple of guests you need the space. With the 2 smaller ovens you lose a lot of space, and you cannot put 2 large dishes in your oven anymore.

For smaller things we use the microwave which also doubles as heated air oven.

We have a very cheap 'air sucker' over the fire, and the wall is protected by a sheet we can wash.
