We've been there for three nights and we really liked it. Although the rooms are little and we didn't have a toilet in our's (only a shower) it's very clean and tidy, and we only paid 35 euros per night. The owners were helpfull and kind, and the hotel it's well located, only ten minutes on foot from Rossio (besides, there's a metro station just at the door, so...).
It's an excellent place for little budgets, so we'll definitely repeat!
