I don't even know where to start. Rene is a wonderful host. We felt at home while 6000 km away from it. The apartment is gorgeous, rooms are spacious, and you have access to many amenities. Grocery store and beach are not even 5 min away, and the train is a leisurely stroll, about 10-15 min away. Rene has the best guide for the area and it is easy to follow. If you want to cook, the grocery store, Pingo Doce, is well stocked, very friendly staff, many speak English and/ or French.
We stayed 9 days and discovered the beauty of Portugal. I highly recommend Rene's place for families with or without kids, from our experience our 3 kids had an amazing time.
Take Rene's advice regarding food, use of transportation as he does know a lot. It will make your stay that much more pleasent.
Rene was very polite, great communicator and very responsive when we had questions. Neuza was very very accommodating as well.
Carcavelos may be smaller but do take time to walk around. We used a combination of Uber and 7-day train tickets to come and go as we pleased. The location of the apartment is perfect as you will never be on the train or bus more than 30 minutes, no matter where you want to go.
Enjoy your stay at Casa Rene.
