What's the square footage of the Family Room with Window?
I am a family of 2 kids and 2 adults and we stayed at the room with a window and two beds. To me, the room size is reasonably ok, not too small till you can't move around. You shd see the budget hotels in Hong Kong, super congested. The bathroom is of acceptable size too but you may find it too small if your body size is big -- may be hard to move around. Overall, happy with Phan Lan 2 hotel. No idea abt Phan Lan 1 though.
I'm unable to accurately give you the square footage of the rooms but as you may be able to see from the photographs of the property, budget hotels aren't spacious. Once you account for the bed/beds, the side table, closet and the end table there isn't a lot of fllor space left over. If significant 'square footage' is important to you, you might want to check into a Western chain hotel at a higher cost. In my case, I prefer to take in the sights and culture of HCM, the fantastic restauarant and street food and pound the sidewalks rather than lounging around my room.
