If you mind some street noise in the late evenings coming from outside, you should look for something else.
If you don't mind, you'll have absolutely awesome experience of living in the very heart of Lisbon in a an apartment which has everything to enjoy it. Fully functional powerful air conditioning, nicely equiped kitchen, washing machine, BT speaker and much more.
Convenience store is two minutes away, historic tram 28 stop is one minute away, metro and some of city's best restaurants are five minutes walking.
Would recomend staying here to all friends visiting Lisbon.
