We had a lovely time! Yes, previous reviews are correct - it is a *very* small apartment, and there is a bit of a 'damp laundry' smell at times. But it's tastefully decorated, located in a gorgeous neighbourhood, and is overall the best value option you'll find in Lisbon.
There are some really thoughtful touches, like the fact that cooking essentials (salt and oil) are provided. Also, the guidance from Cecelia and Pedro about where to go and what to do was invaluable. I'd definitely return here.
