I spent 1 month in Porto and needed a comfortable place to stay and work from home.
There was huge construction work happening for weeks before I arrived and I was not informed by Aposentus Team beforehand. This is poor communication since the city is actually building a metro station right in front of the building.
Construction noises happened from early morning 8:30 am - also somedays going until 11pm at night.
I was really annoyed! Aposentus Team proposed to move to another flat which was smaller and did not worth the price I paid (900 EUR for the whole month with no discount, no commercial gesture).
This is personal judgment but I do not like this "housing agency feeling" that are just here to make money. I had better experience with Airbnb with hosts that were locals and happy to welcome you in their city.
Overall, if you are here just for visits during the day or short time - choose this flat! The flat is comfortable and well located - but do not forget your jumpers, it gets very cold at night.
