My friend and I were staying in Lisbon for a weekend and I'm glad we decided to rent Kleber's apartment.
Kleber is a wonderful host and was always just a message away. He helped us carry the bags and suggested a wonderful Portuguese restaurant where we went the first evening.
The apartment is located right in the center of Lisbon. Sightseeing, great restaurants, and cafes are all within walking distance. The kitchen is well-equipped, so you can cook at the apartment. And even though the apartment is right in the center of Lisbon, it was quiet and very comfortable to sleep in.
The only drawback I can think of is 4th floor, which wasn't a problem for us at all, but for someone it might be a deciding factor. So, just keep that in mind.
Other than that, I highly recommend Kleber's apartment! Thank you very much for having us!
