This apartment is amazing. It has an old-world charm, but is wonderfully comfortable and clean. Everything you could possibly need comes with it. My favourite part, however, is the location; I cannot imagine a better one. I loved Campo de Ourique. It has a true community feel to it and the local park was a fantastic gathering spot.
I would definitely return to this apartment. The hosts seem lovely, although my contact with them was limited.
I have to be fair to others relying on reviews and mention the noise. Firstly, I have read complaints about the construction next door. I really did not find it to be a problem. They didn't start working until 8:00 a.m. on weekdays, by which time my day was well underway, and they didn't work on weekends at all. I know it's a matter of travel style, but I didn't travel to Portugal to lounge in bed. I can do that at home for free. Having said that, if you are a light sleeper, you might find the fact that the apartment is in the flight path to the airport to be a problem. Flights seem to start around 6:00 a.m. Bring earplugs and stay here anyway. It is well worth it.
