Miguel's airbnb is in a great location in Porto, within easy walking distance of most attractions and also very easy to get to from the train station I arrived from. There are two metro stations near by, and plenty of spots for shopping, groceries, food, etc.
I really appreciated the recommendations Miguel provided for places to go or where to eat, and the walking tour he suggested also ended up being a highlight of my time in Porto. It was easy to reach him, and though no issues came up I felt it would be easy to get in touch with him if there were any problems.
The airbnb itself was comfortable and had more than enough space for what I needed as one person. The wifi reached at least 20mbps, possibly faster, and was fine for watching youtube videos though I didn't try zoom. The kitchen had all the basics you would need, and it's only a few minutes walk to the temporary location for the market if you want to pick up some fresh fruit, cheese, meats, etc.
