I stayed with two friends at Juan's for five days and I have to say that is place is perfect for a short trip: well located in the beautiful Alfama area close to Castelo do St. Jorge, clean and fully equipped (kitchen and bathroom had everything you need). It is quite small and doesn't have much natural light, but this didn't bother us as we spent most of the daytime exploring the city. Juan was a great host: flexible, easy to communicate with and sympathetic.
