It was great experience staying at Valeria's. We arrived earlier than check in time and lockers in Rossio train station were fool, so I contacted Valeria, and she let us check in earlier.
The location is really central of city and everything was nearby. There was a heating oven in every room, so we could stay warm in night. Since the flat is located in little hill, it has great view from beautiful balcony. I definitely recommend staying at Valeria's.
