We stayed at Fabio's apartment for 3 days on our first visit to Porto and absolutely loved it. The apartment itself was great, had everything we needed, was very clean and the bathroom and kitchen were lovely. We had lots of towels provided and coffee which was great. The windows are large and open onto a great scene, which makes it feel like a terrace.
The location was perfect, 5 mins from the centre and felt much less touristy. The local restaurants and bars are gorgeous, and there is a great bakery opposite the place. Definitely recommend, very comfortable and easy to get to from Trindade station!
