We had a good time in Lisbon, the apartment is well located, within the castle San Jorge. You have a few little shops where you can buy water, food or other necessities. There's no cars (except a few taxis) in the area and therefore it is relatively quiet and picturesque. Nonetheless, you have a lot of birds spotted right next to the apartment and that could be disturbing if you are a difficult person.
Regarding the house, it has a very nice little balcony and besides the apartment is cosy and spacious. However, the stairs are narrow and sloping, so you have to be careful, but that's part of the charm.
We were a bit disappointed when we arrive because the apart wasn't ready and had not been cleaned. It was 3pm et we were tired from the trip. We had to go out the time the maids clean the house. It was a bit annoying at the moment, but we use that time to visit the castle San Jorge.
We didn't see Joao, but we met Raquel who was nice and helpful!
