if you are looking for a place to just sleep at night this would be it. the location is perfect for walking around Lisbon. close to all the transportation. it is loud with the tram right outside the window. you will constantly hear it. it is quiet around 11pm and the noise starts around 7/8am. I didn't get much sleep.
There are 4 rooms in the tiny apartment building. Only two rooms have a window. It was cool to meet people from all over the world. It gets gloomy inside the apartment due to no windows in the kitchen/hall.
The check in process is easy but if you are not used to the old fashion doors with all the keys you may struggle getting inside especially the door to the room and apartment itself like myself and others staying.
I would say you are paying for location and communication. Not for the physical place. I would stay again if the price was lower.
Elquisson and Julia were very helpful with the communication and information they gave. I appreciated that the most.
