Great location.
You have an option to use two public sea beaches. One in 2 mins walks, another in 5-7 mins. Closest one friendly for dogs and kids :) Another one has a couple of cafes. All of them clean and friendly (sandy btw). One more important thing, if you don't know: this is an ocean side, so you will have tides depends on dates 2-3m low/high.
There are several restaurants on the street. I am highly recommending to try one which is on the same building as apartment. Greate dishes and personal. Tip: use google translate app to translate menu using your phone camera, not all restaurants have an English menu.
The train station in about 10 mins. 10 minutes to Belem (hello yummy Pastéis), 20 minutes to Lisbon.
Excellent apartments. Clean, stylish, cosy and friendly. Gas hob, fridge/freezer, internet, tv. Nice view from the balcony.
Mario is a great host too. Quick response and easy communication.
He also provided "starter pack" for COVID-19 protection: masks and sanitizers.
