The apartment is just as in the pictures, very well located in lovely Alfama, not noisy around and at walking distance from the main attractions in Lisbon. It's also close to public transportation, accessible for cars and a 15 min ride from the airport.
Communication with the hosts was extremely easy, timely and accurate. The check-in was also very easy, was provided with a map and useful tips around the city as well.
One thing to take into account, which wasn't a problem for me, is that it's on a third floor, just in case it mattered.
I would go back to it in a heartbeat.
I had a great stay! Thanks a lot!
