Casa Azul was a lovely Airbnb with a great location. It is right next to a tram stop which was helpful. Alfama is a lovely neighbourhood. Casa Azul was presented as described- small, clean, great location and had most of what we needed. It makes a good base for a few days in Lisbon.
I was surprised that there was no safe (none that we could find) to store our valuable items in. As overseas travellers, it would have been great to have a safe to store our passports/spare money/documents in for the duration of our stay. The fact that there was no safe was disappointing and added some worry. There were a few other aspects to the property that lacked attention to detail and we had a bit of disturbance with the next guests wanting to check in when we had not left yet. The check in process was not entirely smooth and there was some miscommunication there.
I would recommend Casa Azul as a base for Lisbon and with improvements to communication and attention to detail, I would stay again.
