We stayed here for a whole month over August and had such a fantastic time. the flat was great for us, we have a 6 and a 2 year old so we did need to do quite a bit to make it child friendly (more so things didn't get broken rather than safety although some bits for safety). There were a couple of issues with the flooring and a smell in bathroom which I've shared with Fabiana so I'm sure will be loomed at. the WiFi was great, very fast but does tend to drop out ntween 10-11am ish most days.
The location of this flat was the best bit, it was so asy tk get everywhere including an amazing walk into Cascais and the train into Lisbon and Belem.
