We stayed five nights at this accommodation for over £500 in late September 2022.
Pros
1) Location, easy to get everywhere, and beautiful sunset from the big windows.
2) Interior design, great sense of art.
3) Friendly host.
Cons
1) Location, very noisy outside like you are joining a rave party until 4 am.
The days we stayed there were the final summer days with beautiful weather in Porto, so the weekend was like a big festival. Unfortunately, I couldn't sleep (>_<:) Also, it was a bit noisy on weekdays because of the bars with loud music in the street.
2) Amenities, the liquid hand soap ran out on the 3rd day. Only two bath towels and one hand towel for two adults during the six days. (I accepted for environmental reasons, but the accommodation fees were too expensive, with only three towels for six days!)
3) Lack of communication, Luis is friendly, but sometimes I couldn't get replies and had to chase with him.

So, with all these points, it will be perfect for you if you don't mind loud music and people's voice from outside and the accommodation fees of over £500 for five nights without enough amenities in the beautiful one room.
