The apartment was really nice and decorated in a nice way (homy, but not overdone ;) ). It's not big, but the room is well structured so that it does not feel like a very small place. Bed and chairs are comfy. Due to it being a first floor apartment, the room just wasn't as light as in the pictures, but still fine. We had everything we needed for a weeklong stay and the amenities were just as described. Communication was easy and fast and the remote Check-In worked smoothly.
The location is extremely central and a great starting point for exploring the city. You just have to be aware, that the station is literally right next to the apartment so you even can hear the announcement sound and trains coming in and out, which is a bit annoying if you're staying for more than a few days. Also, some (very noisy) construction work is being done on one of the adjacent buildings at the moment. Neverheless, I would definitely recommend this AirBnB for a short city trip to Porto. :)
However, even thoug all of these things are completely fine for a few days and if you are not spending a lot of time in the apartment, but I would definitely not recommend staying here, if you are planning to work remotely. Unfortunately, the internet connection often was not stable enough for videocalls, which was a pity (for everything else worked just fine). During our stay, there also was an intervention by the water company that we were nicely informed of with a day's notice but then someone surprisingly had to get into the apartment during that time - not a big problem, but a bit annoying. The noises from the building site and the train station didn't make things a lot nicer during the day. Long story short: If you're coming to Porto to explore the city and just need a central but still nice place to crash, go for it, if you are planning on working, better find a different place. ;)
