We had a great stay in Patricia’s apartment! It is located in Alfama, very close to Castello st Jorge (les than a five minute walk) and a few minutes away from the Metro. But dont forget that Alfama is in the Hills so you have to walk up, see it as a little exercise (Two elevators are close by, so you can skip a lot of stairs)
many nice restaurants, bars and a supermarket close to the appartment.
There is a very good atmosphere in the neighbourhood and it felt safe to walk at night.
The apartment is clean and it has all the (extra) stuff you need (washing machine, coffee machine, coffee, hairdryer etc). I would highly recommend to stay in Patricia’s apartment!
