Stayed 20 days with my girlfriend, the appartment was great but looked a bit smaller than the picture lead me to believe especially the bathroom.
The pool was great and we got to watch the planes take-off and land, we also got to hear them a lot but it was to be expected.
The sink in the kitchen had a leak so it was impossible to use.
You have a shop near you with decent choice of products and a supermarket right at the corner of the street.
There is barely anything around the appartment, if you want to walk and have a drink you are limited to 2-3 café/pizzeria but the Metro station is close so it is easy to go around.
I'd give the place a 8/10 if you want to chill with someone far from the touristic pressure wich is perfect for me, but if you want to see Lisbonne and feel the streets being alive around you this is not the place i'd recommend.
