This place is amazing, such a beautiful villa with everything you'd need! The garden and pool were just as nice and really well maintained. We went in a group of 12 adults and the place was easily big enough to fit us all! We had excellent weather so spent almost all of the time outside, getting the most out of the pool and the BBQ!
Its a 25-30 min walk to the beach and only a 5 minute taxi to the town of Cascais (well worth a trip for dinner/drinks). Its also easy enough to catch the train from Estoril station to Lisbon (which I think took about 30 mins).
Cristina, the host, was extremely friendly and really helpful! She very kindly allowed 2 of our party (who arrived early) to drop off their things at the house and use the outside area whilst the house was being cleaned. She also very kindly let us use the pool/garden, kitchen and downstairs shower after check out on the last day as we had a late evening flight, this made life so much easier for us on what could have otherwise been a stressful day!
I strongly recommend this place and we hope to go back ourselves in the future!!!
