The building is very close to public transport (and the public transport is really good in Porto), so you can use this to access the airport or the city center and save some money.
The bed is very comfortable and the window isolates well the light and noise so you can surely have a good rest there.
The apartment has also a well equipped kitchen so you can cook or use the fridge to store some food if you want.
I had a good time there with my boyfriend, I would recomend it.
