The location is top-notch - cannot be beat! You're in the heart of everything - very convenient. The flat is well appointed and though the beds are firm you're not left with a backache. The AC in the unit works great and is a welcome relief from the Lisbon heat. The 4 flights of stairs are only a challenge the first time, so don't let them deter you. Its a very spacious and well lit unit where you can be truly comfortable and spread out.
