Excellent communication from the host at all times. Great to have 24hr concierge. Laundry facilities were excellent to have access to. Nice to be on level 15 with view of the city. Easy parking for the rental car and very easy location to large shopping centre with supermarket to get everything we needed (a few hundred meters only). The room was very clean and we had fast, reliable internet. The bed was comfortable and the bathroom was spacious and clean, with a warm towel rail.
The place is smaller than perceived on the photos, it is basically a large hotel room, not really an apartment. It was further from the main sights than I originally thought - but only about 6-7€ Uber ride. It is close to a very large intersection/motorway overpass - so the location wasn’t great, but we didn’t do our research before the time so we didn’t know that when we booked and that is our own fault.
I can recommend this as a more affordable place to stay in Porto if willing to take a taxi or Uber to the sights.
