Just spent 3 days in Lisbon, and Carlos appartment was a great choice. Ideal for 1 or 2 people, the apartment is nice and clean, and probably looks even better in real life than on the pictures. It's also perfectly located in the city, which will allow you to go to the best places of Lisbon in 5-10min walking. Carlos is really helpfull and always responds to your questions, whatever it is. This is why I truly recommend Carlos appartment if you're looking for a trip to Lisbon.
