Very nice, clean, airy apartment.
One large balcony faces northeast, with a stunning view of the National Pantheon. Two small balconies look southwest, with a partial views of the river.
The apartment is reached via 89 steps, after navigating very steep, narrow cobbled streets, so you’d better be healthy and strong in order to lug your luggage.
The Alfama area is very old and interesting, with steep and narrow cobbled streets, lovely views and numerous restaurants.
Do be picky about where to eat, though, as there are a lot of restaurants postings as authentic Portuguese, but are clearly not. Avoid those with people waving you in with menus in hand.
This area can seem a bit rough, with a surprising amount of graffiti and garbage. Much more than in other parts of the city.
The apartment is also close to the cruise ship port, which is not a positive thing, since cheap restaurants and souvenir shops abound as a result of the massive disgorgement of tourists.
There is a train & metro station at the bottom of the hill, which contains the only decent grocery store. Just be ready for some serious exercise on the way back up!
Get daily/weekly passes for trains, busses, trolleys at the train station. Public transportation is really great in Lisbon!
I’d advise heading a bit west in the city and avoiding the touristy commerce square area in the lowlands after a quick peek at it.
