I spend 3 weeks at Carlos' place, working remotely. Communication with him was super easy. The apartment is well equipped with everything you need, internet connection never failed, and the bed is really comfy. I also really appreciated the lift as the apartment is on the 4th floor. Staying there made me quite the Tejo fan - I loved the view from the window, if you look to your right you can see the river and it's ever changing colours.
