I stayed at Barrio Alto Suites and loved the experience. I arrived very late in the evening. The check in was available by phone and through using a key pad system. A friend arrived the next day while I was out for coffee and he was able to use the key code in my absence. It was super easy!
The accommodation is located on a lively block that is fun to walk around for nightlife, coffee, eating and other entertainment. I am thrilled to have stayed here during my time visiting Lisbon.
