I stayed for 14 days and it was a bit far from the city center, so it was not noisy and it was very convenient to move around.
There is also a large market close to the house, which was very helpful for long-term stays.
The room I stayed in was a bit dark and the soundproofing of the building was not that good. But internet was fast, hot water and heating equipment were well prepared.
And the host, Muguel, was very friendly and responded quickly and kindly to all inquiries. Even though I arrived late at night, he personally introduced me to all the houses and gave me detailed information about places to visit in Porto and important information. :)
