Just perfect. No fussing around for checking in, no keys to pick up in some shop, no keys to leave somewhere, no bizarre instructions, a super fast wifi, induction plates if you want to cook, enough utensils for some basic cooking, a microwave, a toaster - everything you need. Very comfortable bed, soft bedding, and extremely quiet - we slept like babies.
I’ll be back here for every one of my coming trips to Berlin.
