It would be much much better if the mattress was replaced because it's really bad and unconfortable (there's a hole right in the middle and you can feel the mattress springs on your back). It's an old building, so expect old building issues - bad plumbing, squeaky floors, neighbour's noise among other things. There was no bugs but it wasn't clean at all, though the cleaning ladies had just left. I had to clean it myself upon arrival and desinfect all the surfaces. No lights in the hallway and you'll need to be persistente to open the main building door. The location is really nice, right next to Praça das Flores, with restaurants and a nice vibe without being too noisy at night time. Very close to Príncipe Real and you have all the transports you need 10 minutes away (subway, train, bus, eléctrico). You'll pay for the location. If you're on a budget, you're flexible and can overlook all the issues, this can be the right place for you.
