First of all, I recommend this house and the host to all!!
Location: near from the center and very quiet. You have to walk a little bit long from the center, but if you take a train, you can reach the house very quickly. The area this house is located is very quiet, so I think you can relax and sleep in the house.
House: excellent!!!! The house is the best I have ever stayed. Very large, clean, decorated, sooo many amenities... There are two bedrooms, one kids room, one living room, kitchen, two bathrooms, and a terrace. I'm sure you are surprised at the interior of each room. You can enjoy everything you want in the house: cooking, drinking, chilling,.... This room is well equipped with anything: so many cute table wears, laundry detergents, travel books, and so on.
Host: Great!!! The best host I have ever seen! The host welcomed us at the house and she politely told us about the house and the city: how to use the kitchen and the bathroom, how We can go to the center, where we should go in Porto, the interesting internet site about Porto, and so on. And also she made cute and delicious dishes for us! We ate the dishes as a first meal in Porto and I think it the best in Porto!! And, when I wanted to know good shops in Porto and asked her about that, she texted me her recommendations very quickly! I think this host make your trip to Porto greater than you expect!
In sum, as I said first, I recommend this house and the host to all. I'm sure with 100% confidence the house and the host make your trip excellent!!!!!
