This apartment was beautifully done and very pleasant to stay in. Location is central. We also screwed up the dates (we booked the place last second and for the wrong week). Host accommodated us, and quickly changed the dates and met us to let us in within 30m! It was super clean. Beds were great, linens high quality and we were able to rest really well. Chocolates and wines that welcomed us were delicious. Host was very responsive (we had questions on local businesses) and pleasant.
I would recommend this place to anyone and would go back if we ever visit Porto again. It was by far the best designed layout and use of space I have ever seen. The only minor drawback was that the TV was super old. But who had time to watch in a beautiful city in a wonderful location. 5 stars!
