Carla's place is an awesome place to stay in Porto. The interior of the flat is very stylish, all appliances and furniture was modern and clean. And the hosts are very helpful and easy to communicate with too!
To get to the flat, the hosts offered to pick us up by taxi (which I think is a great option), but we thought we would get there too early to check in so instead we took the metro. If you decide to take the metro, get down at Marquês station - the flat is just a 5 minute walk from there. It is best to contact the host when you get to the station so they can show you how to get to the flat as this is inside a building in a small mall area.
Carla's place had everything we needed, we were able iron clothing which creased in our luggage and even make grilled sandwiches for breakfast - it is a great place to stay while in Porto and I would love to go back and stay there again!
