Miguel is a wonderful host. He is well organized, easily understands the sort of experience you are looking for and takes the time to efficiently guide you and to answer all your questions. We were impressed with his excellent qualities as a host.
The downtown apartment is in good condition, and has all the amenities necessary for a pleasant stay, in our case for 9 days. Beds are very comfortable, kitchen is well stocked and has most appliances and basic stuff (excellent olive oil!) that you would need. The area is quiet and safe and its location is close (walking distance) to many of the interesting places that you can visit downtown, and also to metro and train stations to reach the seaside or the nearby historical towns.
We have also found that the people of Porto are welcoming and helpful and overall had a great time, and for this in particular we would like to thank Miguel and his well thought out place.
