In just a few words: Miguel's apartment was amazing! It's located in the best area of Lisbon, the old Alfama, a maze of little alleys and cobble-stone ways, little cafes and restaurants with the traditional Fado music. Here you feel the authentic Lisbon!
The apartment itself is extremely well furnished, with everything you could possibly need. It's bright and sunny but doesn't get too hot inside in Summer.
Miguel was also quite helpful and forthcoming. I definitely want to go back soon!
