I had an amazing time in Porto and the location of Mario's studio really contributed to it. The neighbourhood is safe although any smaller street in Porto needs to be navigated with caution at night. I managed to visit the entire historical centre on foot as it is located near great bars, restaurants, attractions and is only a 30 minute walk away from the Douro river. The space was small but comfortable, the noise level minimal although the stairway does echo, and on the weekends occasional street noise can be heard if the ppl passing by are loud in nature. The bed is super comfortable and I slept really well! Mario was responsive and made my arrival easy, providing me with some notes on the area and a map.

That being said the supplies in the apartment were lacking. The kitchen was well equipped with utensils but no napkins, paper towels, or even a dish towel were provided for ease of cleanup. TP was also low (1 1/2 rolls) and I would have brought it up with the host if I hand't realized the shortage just before leaving. There was very little dish soap and even though I didn't use that many dishes it sucked to find someone else's hair on the dish sponge when I went to clean up on my final morning! Thankfully the linens and bathroom were clean and the surfaces free of dust.

All in all though I think these are all points that the host can fix, and would have likely fixed had I had time to tell them about it. So I would still recommend the space to anyone who wants a centrally located spot in this beautiful city.
