La casa do Poeta is a great location if you want to visit Porto. Central and clean, we got around without using any public transport.
The apartment is sparkling clean and very minimal and stylish. Fully equipped and good communication with the host.
During the day you could hear some noise coming from the neighborhood (cars, works, people, stairs...), so keep it in mind if you are looking for a calm and quiet place. We have been asked to do the check-in at the agency which made us do a little detour. During the explanation about the house and its equipment we felt a bit threatened when we have been told that we would have risked an extra charge of 300 euros if we did not use the flush of the toilet properly.
Other than this, recommended.
