The apartment is cute and offers everything you need. Wi-Fi works, it has a small TV and nice corner if you want to relax and plan your trip for Lisbon. Walking distance to the city center, Raj's market a few meters away to buy water, morning coffee and small pastries to eat something quickly in the morning, if you don't have plans to wake up and cook. A bit noisy in the morning from cars passing by, but some earplugs for the sensitive ones will do the trick. It is a small apartment, so light travelers will manage. I would say perfect for 2 people. You have everything you need for a short city visit.
Ana and Raj also helped us with parking tips. We walked most of the time, but had a rental for the last night. You can park for free in front of the apartment from 7pm to 9am, if you find a place.
Communication with Ana was quick and smooth. Nice and always helpful :)
