Sarah + I arrived during the festa de Santo Antonio. About two or three weeks before we were going to check in though, Rui messaged us warning about the noise during our stay. He offered us a full refund if we decided we couldn't stay here due to the noise.
We decided to remain in the area and we are very glad with our decision. Alfama was by far the liveliest neighborhood during the festa with people of all ages celebrating during the event.
This place was perfect for what we wanted and we had a blast. Highly recommend to any travelers.
