Ana's apartment is located in a nice district that is close enough to all the downtown Lisbon attractions while being a little bit off of the main thoroughfares. The apartment is clean and has all the amenities you would need. There are nice blinds that keep out light and any prying neighbors (who are right at eye-level). There are two things to know though:
1) The walls/windows are thin. You can hear people/a train running so if you are a light sleeper this is not for you.
2) The A/C units are nice but the light on the one in the bedroom is so bright that you should be ready to cover it or turn it off at night if light bothers you.
