We were a family of 4 coming for the 1st time to visit Lisboa. We really enjoyed the flat of Ricardo ! The flat is really nice, very big and in the center (we did everything by walking!). As it was February, Ricardo put heaters for us in every rooms so we were not too cold. As it's in an old building you can hear a little bit noises from outside but that's not a big issue. We would definitely recommend the flat to friends&family!
