We strongly recommend Diogo and Rita's apartment. It is located in a lively and centric neighborhood with plenty of restaurants and cafés, with great access to public transportation. It is very convenient to reach basically anywhere in Lisbon and its surroundings. The apartment is very well-lit, and the kitchen area with its large marble-top table and the large patio is truly priceless. We used to spend all the time there! Despite its location on a very busy street, the apartment is very quiet at night and we always slept well. Diogo and Rita were great hosts and they went all the way to make sure that we didn't lack anything (they even brought new furniture during our first day at the apartment just because we mentioned that we were there to work and one more table would be great!). This is a great place to stay in Lisbon (we spent here one month) and we would not hesitate to book again.
