Found this listing at the last minute en route from Porto. Apt was located in a quiet residential neighbourhood not near to any major attractions. There isn't much food around unless you are prepared to walk 10mins to the main street. We found Ramiro's which served the best seafood ever in Lisbon.
We didn't use the Metro at all despite the proximity. Uber is super convenient.
House is very dated (I believe it's built in the 70s) but clean. There's a noticable smell of bleach I presume was due to the cleaning. Fixtures and appliances were ancient but generally in working order. House is generally clean but the bathtub has black slimey residue under the rubber mat. We did not dare to use the tub at all. Hot water only sufficient for 2 pax and it takes ages to heat up in winter.
Do note there is no air-conditioning. There is a small heater for the winter nights.
The unit sits just next to the street, so be prepared for road noise and pedestrians chatting and talking along the pavement.
