This place is absolutely wonderful! It is perfectly located basically next to the Clérigos tower, near many restaurants, bars, shops, grocery store(s), and a close walk to a main train station (São Bento). Basically, it was close to everything I wanted to see during my short time in Porto. Further, the place was extremely nice. Very modern and clean. The wifi works perfectly. Mário is a great host as well. He was very responsive via text message and was there at the door right when I arrived. He also gave me a very useful map of the city and a lot of great recommendations. I highly recommend this apartment. I will definitely stay here again when I make it back to Porto someday.
