Great, really well located home. Walking distance to loads of great food and drink places, including one of the best pastel de nata places (where we went for breakfast a lot).
Maria and her husband were great hosts, and gave us fruit, cakes and wine when we arrived which was above and beyond what we expected. They were very communicative and even let us check out a bit later when our flight was late.
Only thing to be aware of is the noise of Erasmus corner which is very near to the flat. I personally didn’t mind, and was still able to fall asleep even at the loudest times, but if you’re sensitive to noise or want somewhere very quiet I probably wouldn’t stay near the busy spots in Barrio Alto.
