Cais is a really beautiful place. The colours, the bathroom, the kitchen, the location. If you are going for a citytrip and you prefer beautiful stay, this is the place. I will definitely recommend it to my friends when they are going to Lisbon. Nuno, the host, was very friendly and responding super quickly. It is in the centre of the city, so there are noises of the nightlife, but did not bother us at all. Enjoy Lisbon!
