The apartment is perfectly located on the other side of the river Douro, opposite to the city of Porto, with everything that's needed in a walking distance. Being near to the Jardim do Morro, probably one of the best places to watch one of the breathtaking sunsets (and there are quite a few!!), is definitely a huge plus.
The apartment itself is spacious and clean and comes with all amenities one could wish for. We especially enjoyed having a washing machine which turned out useful after having been on the road for some time already. Also, the terrace is a nice place to relax from a busy and exhausting day.
Even though the apartment looks a bit different on the inside than what the photos might suggest (f.e. it's an apartment on the ground floor/souterrain and doesn't come with large windows, so it's darker than expected), it's worth the price being affordable and rather cheap compared to apartments in the surroundings.
If you're looking for a nice and well-equipped apartment not in the middle of town, yet pretty close to the centre, I'd definitely recommend staying here.
