João is a great responsive host who really wants to facilitate the best experience of Lisbon; he gave great recommendations. The apartment itself is very clean, petite but comfortable with room where you want and need it, and had great soundproofing on the street-facing walls. The neighboring apartments can be heard because the building is from the early 19th century, but the tenants are respectful, not noisy, and keep hours that made it very easy for me to get a great nights sleep, even on the weekends (and I am a light sleeper). I would choose this apartment over hotel room noise for sure. The proximity to St. Apollonia station and Alfama make it a great choice if you want to spend the day exploring the city and have access to a kitchen and washing machine.
