We have just returned from a 5 night stay in this studio and would definitely stay again!
The location is great as there is an abundance of things to do which are all easily accessible. The train station is only 5 minutes away but the studio is not noisy. You can reach Cascais in 10 minutes and the centre of Lisbon in 20 minutes. There is a supermarket, local shops and restaurants just 5 minutes away. Plus the beach is only a 10 minute walk away! Catarina was very friendly and helpful, offering advise where needed and pointing out all the local amenities. We thought the studio was well equipped and comfy. Travel and food were cheap compared to England and just bumped up a little in tourist hot spots.
PS just be careful of cab drivers over charging from the airport (We got caught out)More
