Glou was the perfect accommodation for us (a couple exploring Tokyo). The room is compact, clean, well priced and got everything you need, with a very nice bed! The neighbourhood is also perfect, as it is located in a very nice quiet street, but within 10 min walking of Shinjuku's centre with all the beautiful shops and restaurants. Also, there is a subway station in less than a minute walk, that easily connects you to all the major metro lines and other neighbourhoods.
The staff was very friendly and super helpful. We had some logistical problems and they helped us out a lot by any means necessary. Also, they were able to contact restaurants and bars for questions and reservations, which helps a lot as the restaurants generally don't speak English.
Overall, I would recommend Glou to anyone who is looking for a perfect clean budget hotel on a pristine location, with the best staff you could wish for!
5 stars!!
