We loved it here. We came with high expectations which were fulfilled, so what can I say? We were in Lisbon for a congress which itself was near Oriente Metro station. The walk down to Martim Moniz Metro is quick and easy so we did that every day, enjoying it a lot. Also, walking back up is not the ordeal people would like to make you think.
There's a ton of restaurants and pastelarias neerby and we were never once disappointed, so starving to death isn't an issue.
