We stayed in Idea lab’s apartment in Sintra in August and had a fantastic stay. We stayed with another couple and their baby for a friend’s wedding and it was the perfect base. Because of the heatwave, air conditioning in every room was very appreciated! Communication regarding the flat was really prompt and we received a very warm welcome when we arrived with suggestions on where to drink and eat. The apartment is incredibly clean and has everything you need. It’s also in a great (and quiet) location within walking distance of great bars and restaurants. Overall - we would highly recommend this apartment to anyone wanting to stay in Sintra
