Evolver has three rooms divided over two floors: downstairs there's Action Park (live room, bigger of the two) and Utero (the smaller one, an iso/amp room). Both rooms are divided by glass sliding doors, offering a line of sight between the two rooms in case you'd want that.

Guitar amps and/or cabs (amp heads could be left in the live room) will most likely be put in Utero, drums and band members will be at Action Park. It is perfectly fine to mix this up, there's enough space to do so. Putting drums in Utero will give a more close-up room sound.
Action Park's floor space is not huge, but the room has quite a high, sloped, ceiling. Its lowest point is at 3.2m, going up to approx. 5.5m. Big drums galore indeed. There is more than enough space to host full sessions with a significant number of band members in addition to a drumkit. It is also possible to record full bands in the room, if we're willing to embrace the bleed and settle with a less than ideal room sound for drums.

Utero is big enough to host a full drum kit and some, but offers a perfect chance to separate loud blasting amps from a drum kit during live takes. It can also be used as a vocal booth while the entire band is going at it at the other side of the glass in Action Park.

Upstairs and on top of it all is Head, the cozy control room. This is the mind of the studio where it all comes together. It is big enough to have a group of 4-5 sit comfortably while listening to the results of our efforts. Bigger band? We can always grab a pair of chairs so you won't have to sit on the floor.

There's also a kitchenette upstairs, with good coffee readily available 24/7. Cooking a simple meal is possible, but there are also numerous options available for takeout.
Basically, there is no option for lodging/accomodation at Evolver. There are affordable alternatives nearby.
