Joana's apartment was awesome - very spacious with a beautiful view. I felt really great with the glass of porto wine on the couch after long day of exploring Porto. It's not in the heart of the city but you can easily reach the historical center with using the way through the private garden (which is beautiful too, btw). Joana is very nice person and she did her best to make our stay comfortable. Her tips about the public transport was very valuable. Highly recommend this great place for everyone who would like to experience Porto!
