Overall, the appartement was a very nice and cozy place in the centre of Porto. It was clean and neat and looked exactly as pictured. It couldn’t be much better located.
As others have mentioned, the heating is currently not working.
There was however a mobile heater, which was good as a temporary solution.
Also, the construction happening in the neighboring building (starting at 8 am most of the time) was quite a bit closer and louder than expected. It didn’t really bother us as we spent most of our time exploring the city, but for long sleepers or people who spend most of their time in the appartement, I can imagine that this is an important thing to consider.
