Rodrigo was a wonderful host. He offered to pick us up at the airport (for a fee) which we accepted after flying in on two flights from the west coast of the U.S. The apartment is centrally located with very easy access to many things. Go up the hill to my fav part, the Bairro Alto where you'll find really nice restaurants, markets, shops, healthy food places (I like healthy stuff), two blocks to the famous Time Out market/restaurants, a few blocks to the trains to Cascais and water, and also a short (~10-20 minutes) walk to main squares and shopping areas. We like to walk and don't mind hills so it was great.
The apartment is small and what I call typical AirBnB IKEA. We are now in Cascais about 18 miles away down the coast, and the kitchen is identical. It is absolutely perfect for short stays. I always wish places offered more towels, but there was a washing machine we could have used. I will echo others' comments - it is noisy at night, and we were not even there on the weekend. I had packed earplugs based on other comments here and that definitely helped - jet lag always helps too - haha! A giant plus and rarity: the building has an elevator which was great for my too heavy suitcase with a third floor (which is 4th in the US) apartment. The wifi was excellent - my husband had some work and it worked well.
Again, so happy with Rodrigo's hospitality, restaurant suggestions, and responsiveness. We had a great time!
