Pros:
Large space ideal for 2 travelers. Enough room to do yoga if you have a mat. There is a dining table which can serve as a workspace. The kitchenette is small but has enough if you want to do some simple cooking and heating up. Olive oil, vinegar, salt + pepper is provided and even Tupperware if you store things. Kettle for hot water and nespresso coffee machine with 2 comp pods. Complimentary disposable masks provided. Walking distance to everything. Bed is nice and at night its quiet. The team are responsive and had the good intention of assisting with any questions we had. The washing machine is a small one but sufficient for short stays and they provide the washing powder (though they need a full-sized drying rack + ironing board). AC cools well the entire flat. Good blackout blinds. Bathroom is large, water pressure + hot water very good. Wifi works well. There is hanging closet space (but sparse shelving). You have the full top floor and the double-volume ceiling feels extra spacious. Cool views as you're in the thick of Porto! Parking lot is a garage with 24-7 security so its safe to leave your car overnight.
Cons:
The parking is off-site and due to construction you'll need to ask them for the exact directions to get to the entrance b/c Google Maps is not able to help. If you're traveling alone I'm not sure how you would navigate that b/c one person has to run up to get the key to the parking lot (up 5 flights of stairs) then bring it back to access the parking lot. You'll unload your bags and then bring them to the hotel - you'll have to circumvent the construction but this is easy.
5 flights up and no assistance with bags - not a big deal but just FYI
It's noisy in the day due to construction on both sides of the building and as some reviews have mentioned, the main street is busy during the day. Unfortunately we could not open the doors to make use of the balcony on either side as a result. Not a big deal if you don't spend the days there. If you close the doors you can work and its quiet enough.
We used earplugs b/c the noises start quiet early in the morning, but were able to have a good sleep there.
If you're new to the area, no guide books or recommendations for Porto but if you message them with specific questions they can offer some guidance.
You decide!
