We had a great stay at Sarah and Pedro's apartment in Santa Cruz. It was a lot quieter and more comfortable than our stay in Alfama on a previous trip to Lisbon, and there are lots of cafes and shops for groceries etc (including a local supermarket within 5 minutes walk). We took the metro to/from Anjos/Alameda to access the apartment, but we also walked in the centre of Lisbon on one day (it's downhill) and it wasn't that far really. The apartment is very clean, spacious and modern, the bed is big and comfortable and the shower is powerful. WiFi was good, although better signal in the kitchen/sitting area than the bedroom. Check-in/out was hassle free and easy and communication with Sarah and Pedro was great. We would definitely recommend.
