We really enjoyed our stay at Judite's and Porto Deluxe place. Everything was brand new, and beds were by far the most comfortable during our stay in Portugal.
Judite's team is amazingly fast and detailed with all communications, and given the keyless system the check-in / check-out was a breeze.
As described, the apartment is super clean and modern, and everything works perfectly. Despite the location on a major avenue, it is also very quiet because of great noise cancelling windows. Wi-Fi works very well across the entire place.
On the opportunity side, I'd only recommend installing the washers / dryers in the building. I understand that the team manages all or most of the apartments in the building (and a few others nearby) -- so it would be very handy for many guests.
We look forward to another stay!
