I would highly recomend Saras house if youre visisting Lisbon. Its very well located in the Alcantara area, there are tram stops very close to the house which take you to the centre in 15 minutes or so. The house is very clean, comfy and with a lovely patio to relax before bed or to have breakfasts before setting to visit the city.
Sara kept in contact with us throughout our stay , always willing to help or to provide any advice, shes being a great host.
