My girlfriend and I spent a few days in Porto in April 2019. Our room was lovely, backing on to Nahir's delightful garden and had some amenities - a small fridge, a kettle, french press etc - which was a nice touch. We were a ten minute walk from the centre of Porto, a bit more to the riverfront and a five minute walk from a supermarket.
Nahir was kind and thoughtful providing us with some tips and recommendations for our stay. We'll be booking with her again when we return to Porto!
