I just went recently to Porto for a work trip and stayed at Miguel's flat. It was the perfect choice for me. Very comfortable bed and spotless clean. I didn't have to use the kitchen, but all utensils were there.
My flight arrived late in the evening, and Miguel didn't mind the past midnight check in. He's a great host, very easy to communicate with.
As extra touch Miguel, very kindly left some oranges, bottled water, biscuits and homemade honey /jam for me.
The location is excellent - just seconds away from the main attractions. But also very close to trendy Cedofeita restaurants and shops. If you're a coffee lover like me, the flat is around the corner from the best coffee shop in Porto (Cafe Progresso) and Zenith (for yummy brunches & cocktails) you'll see the queues outside restaurant in the mornings. Also there is an excellent Peruvian restaurant a minute away called Panca, worth visiting if fancy a change from Portuguese food.
The flat is located at the front. So on Fri & Sat eves you might hear some noise from the streets - but I didn't find it disturbing or that interrupted my sleep.
This is a great flat which I'll be happy to return , if lucky enough to be back to gorgeous Porto.
