We stayed at Helena’s place for 20 days. The place is immaculately clean. It is very close to the beach (about 10 mins walk) and it has everything you might need in a flat. We love the area (we know it quite well and couldn’t recommend it enough). Communication with Helena was easy and she responded immediately to our questions. I wholeheartedly recommend Helena’s place if you want to feel like a local in a really nice area of Estoril.
