We had a fantastic time at António's apartment - it was simply perfect for our needs - compact, clean and easy to access, we were able to dart in and out in between exploring the city.
António himself was fantastic, we were late to arrive due to public transport issues, yet he patiently waited for us and welcomed us warmly. He quickly showed us round the flat, then left us to our own devices, promptly sending over recommendations for where to eat (which were all dead on).
Would fully recommend this quaint little apartment for any couples/individuals who want to fully immerse themselves in the hustle of the Alfama (old town) - though the area itself was actually very tranquil. Bravo António!
