The apartment itself is really nice and in a great location in Graca. You have in my opinion two of the best miradouros for sunsets within walking distance. There are also some super nice traditional restaurants close by. As for constructive feedback. There is a very small wardrobe for clothing in the bedroom so if you're staying longer than a week this is not ideal. I suggest to allow for a 30-40 min window for checking in guests. We arrived a little later than anticipated and where just handed the keys without any guidance. This resulted in us being challenged by the lock to the front door and needed to call for assistance. I did request a bread knife to be provided as there are no knifes with a serrated edge to cut a loaf of bread. This was declined. So we were left cutting bread with a butchers knife. I consider this a basic item. Lastly the floors were super dirty so walking around barefoot resulted in black soles. We had to wash our feet in the shower every night before going to bed. Not an issue if you don't walk around barefoot.
To conclude I would recommend this apartment and its location. I hope the constructive feedback is taken into consideration to make others peoples trips more amazing.
