well, nothing so much to expect from a very cheap cost per night room stay from more than 100 old heritage guest house located in the center of Macau. It's very few minutes walks from the Senado square, few more walks to Grand Lisboa and St. Paul ruins.

there are a lot of authentic Macanese resto nearby, cheap eats. It's perfectly located at all your needs (drugstore, mcdonalds, 7/11, supermarket etc etc). Easily located and well known guest house for taxis. But to avoid problems upon your arrival, better print its name and address in Chinese characters (provided by the hostel reservation officer when you reserved online, do make reservation atleast a month because it's always fully booked), as not all drivers can speak/understand English.

Well, our room is two beds good for 4 people (we are three), quite big space with good ventilation, no airconditioning or heater, clean sheets.
BUT.... the room is made of thin wood-walls so you can hear all the noise at the other room and corridor, well, it might be "peaceful" sleeping IF OTHER GUESTS are considerate enough and do care enough to LOW their volume when talking. The guest house mostly occupied by Chinese people from mainland China and I guess, that's explains it.
there's free water at the front desk, bathroom is common, so you gotta bring your towels, soaps etc and be sure to be there early as there's only two showers available per floor.

other than nothing to complain, it's safe, it's ensuite with cameras and all.

suggest to the owner that since rooms walls are made of thin wood, they put signage saying "OBSERVE SILENCE AFTER 9:00PM until 8:00AM" or "BE A CONSIDERATE GUESTS, PLEASE LOWER YOUR VOICE."
