Great apartment, overall I highly recommend it.
Pros:
1. The apartment is modern, clean and comfortable.
2. Lots of dishes and kitchen utensils. There's also a dishwasher and a stove (though its electric spark for burners doesn't work).
3. Big bathroom and shower with a huge mirror.
4. New building with an elevator.
5. Conveniently located and close to everything - 2 metro stations, buses, several grocery stores, cafes, etc.
6. Very quiet. Good soundproofing and all the windows face a quiet yard, not the noisy street.
7. Friendly and helpful host.
Cons:
1. The remote controls for ACs were for some reason hidden in the drawers. But the host told us how to find them.
2. The oven doesn't work - there's a sign "Out of service" inside it. Oven is not stated in the apartment description, but it's clearly seen on the pictures, so we expected it to work, which was a bit misleading.
3. The air extractor above the stove is not working.
4. There is no wardrobe for clothes.
5. There was one neighbor, who used to talk by the phone for hours walking in the yard, which was really disturbing, as he was clearly heard from the apartment.
6. I'd say it's a bit expensive, but it's common for Lisbon.
