It was a rude shock when we opened the door to our room. If you have ever shared a freshman dorm, the standard room at Santo Inn Grande is smaller than that. I would definitely not recommend this hotel for people with claustrophobia. Low ceilings complicate the whole thing.
When you check the amenities, it seems there is everything in 15sqm / 160sqft. There is a bath-tub, but it is half the size. The shower is half the size. Sink is right near the bed, which is yuk. It is a scramble to have 2 people in the room. Pictures on their website are deceptive.
Front desk seems friendly, but keep a translator handy.
If there is one positive, it is the TOTO toilet seat which is high tech, but that too is in a very tight space.
