We traveled to Lisbon for a short vacation and had a great time at Miguel's place.
The flat looked exactly like it does in the pictures, and the views are amazing indeed.
It's 7-10 min drive from the airport, and you've got all you need in the neighborhood, which is conveniently located (the second biggest aquarium in the world, the Lisbon Oceanarium, is just a few minutes away from the flat! So is the Vasco da Gama Shopping Center :-) ).
Miguel is a super pleasant host. He was helpful from the beginning, and always in touch whenever needed.
Totally recommend staying there!
