Very clean, modern looking apartment in a great location within easy walking distance to major hotspots. Several balconies in the unit with descent views were great for relaxing in the evenings over conversation and a glass of port or wine. Communication with João was good and he was generally responsive. A nice bonus, the apartment has a washer (but no dryer) in unit.
As far as negatives, there were a fair amount of stairs to climb (great for exercise to work off all the fantastic Lisboa food we ate but difficult for check-in and out with luggage). Apartment also lacked closet / shelf space for organizing and storing clothes / luggage.
