This place is IT. Stay here. The building is very secure with a beautiful entry, a lift to help with luggage and strollers, and an easy keypad for quick entry. The layout of the apartment is terrific, with an amazing little balcony to soak up the culture and play cards at night listening to the sounds of a very vibrant small city! The kitchen is well equipped, and there were lots of extras (towels, toys, books, sand toys, high chair, crib, blankets) including a welcome gift of wine! The location is absolutely perfect, right in the heart of old town on a pedestrian street. SO many amazing food options around and a 3 min walk to the beach. The best parking was at the train station (~7min walk away/$12 night) but there was a loading zone parking spot across the street for drop off and packing when we left. We loved Cascais so much we didn't want to leave. It has all the best of a large city with a quaint feel of a small town. We found several local parks (check out the one with the children's library that has several bird species living on the grounds!) and drove out to Guincho beach and the dunes, all very beautiful! There seemed to be a great bike rental scene with a promenade all along the coast but it rained while we were there, but would suggest doing that too! Overall, this was our favorite Airbnb in Portugal hands down! Paula was very responsive and a great host!
