Abel’s place is great! It is very spacious and modern with a perfect location that was close walking distance to transit/metro and to tourist attractions and restaurants. We rented a car and there was an underground parking garage less than 200m away - 30 euro for 24 hours. Because of the location, it is very noisy at night from the nightlife and in the morning because of construction in the building. If you’re looking for a solid sleep, I recommend ear plugs. The beds are a bit hard but they did well for our one night in Porto.
