Can definitely recommend it.
The only possible downside you should know about is you have to leave your capsule from 10 am to 4 pm, even if you're staying consecutive nights. But it didn't affect me, since I was running around outside all day anyway, and also it's possible to leave your belongings in the locker during that time, so you don't have to carry everything with you.
Everything else was superb! Good location, free sauna, TV, fresh pajamas and towels everyday, very friendly personnel, easy check-in and check-out, ... Be sure to bring some earplugs though, because you might hear your neighbors snoring.
