Our stay at GLOU was a great experience. The room was very clean and had all the necessities for a short stay.
We were expecting a larger room given the price but we were still able to fit 2 large luggages in the room and could maneuver around.
Be aware that it is very close to a subway station, but it is not on one of the major lines (most likely you'll have to transfer). It is very close to convenience stores which was a huge plus.
