We stayed here back in March and enjoyed our hosts and the apartment so much that when the opportunity arose to return to Porto in October, we rushed to book this place. The experience was just as good as before and we cannot recommend this place enough. The kitchen is small but well-stocked for basic things like coffee, tea, and breakfast, and with the number of bars and restaurants practically right outside the door, this isn't the place to be cooking gourmet meals.
We took advantage of several of Alice's suggestions, including the "best ice cream in the world" (true!) and a day trip to the Douro Valley. Porto was in the middle of an unseasonable heat wave while we were there, and the air conditioning was greatly appreciated.
If you want to stay near the action of the city, but not worry about noise, enjoy a modern, comfortable apartment that still has Portuguese charm, and interact with marvelous hosts, book this apartment!
