We only stayed here one night before heading to Lisbon airport. The location was very good - close to the Lisboa Oriente train station (trains from the north but also a metro station there going to the airport). We were in a Premium Room, which meant a coffee machine, fridge, robes, and a nice bathroom. The room felt a bit nicer than the Ibis-standard I am used to.
The main problem was the aircon - it just did not seem to do anything, the room was far too hot, and our sheets were drenched in sweat. The staff did say it was unseasonable warm, but I don't know how this hotel could cope in summer with that aircon system.
