We spent a nice short vacation in Alfama III, which is centrally located in Alfama. The nights in April were a bit chilly and the powerful heater/cooling unit was handy.
We recommend the small Pastelaria Alfama Doce very close to the apartment: pastry & coffee were excellent and staff were friendly and spoke very good English & French.
Ulrik was friendly and quick in his reponses and he provided nice information regarding the apartment, Alfama, and Lisbon via email.
