Great place to stay for value in Lisbon, a little out of town centre (takes at least 40-60mins) to visit attractions with public transport but you can experience what it's like to live among the locals :)
The room itself is clean but it may get a bit noisy sometimes at night since the room faces the streets and Portuguese cars may get lively on the music, but I had no trouble sleeping since they're only passing by even though I'm a light sleeper (maybe I was too exhausted).
