I had a great stay at Glou. The front desk staff were very nice.
The room itself was great- just big enough to store my bags and have a great sleep on the large, comfy bed.
It’s a very short walk to Shinjuku, but far enough away that you’re out of the madness. Even if you don’t have any interest in Shinjuku, I’d still recommend this place because of its close proximity to multiple types of transit.
