I booked the apartment for two friends and their two kids, so I’m giving feedback on their behalf. They gave 3.5 in average. The apartment is well located, equipped with essential things, in general it’s ok to stay for one night. The shower is not very good, and you will have to get your morning coffee or tea somewhere else because there is no pot to boil water (luckily there are good cafés everywhere in Porto). A very important note is that there is only one shared lockbox to store keys which other people staying in the same building have access to too. It is a bit strange for safety reasons, could be improved. The whole building is used for Airbnb, so if you are looking for a stay-with-the-local experience, this is not the right choice. In addition, guests in other apartments coming back late could be quite noisy, so good luck. The apartment manager Isabella is responsive and helpful.
