My family of 3 loved this apartment! We wished we planned for more days in Porto. The location was perfect for exploring the city, especially if you don't have a car to mess with. We rented a car to visit the wine country - and don't regret doing so (highly recommend visiting Pinhao and the Douro Valley) - but parking options in Porto were not convenient, especially with the construction and traffic congestion.
The beds were very comfortable. We loved the balcony to enjoy our wine at the end of a long day exploring. We didn't really take advantage of the kitchen much, but it looked well stocked. Had we stayed longer, we probably would have used it more.
We very much appreciated Valentin's recommendations and suggestions for an enjoyable visit to Porto. Joana and Valentin were both very friendly and responsive whenever we had questions. (Thanks both!)
Other than some plumbing issues, the apartment was perfect for us. We would definitely stay again for a longer, more relaxing visit someday!
