The apartment has a great view. It is centrally located. I walked everywhere in Lisbon but the subway is also very close.
Nuno responds very quickly and he offers a lot of information for exploring Lisbon. I would recommend this place to stay. It is located right on the outskirt of the Barro Alto District so you turn a corner and are at the party. It was perfect for me, but may not be suitable for a more conservative guest.
