This apartment is in a nice location and easy to walk to many places. It is clean, nicely furnished and comfortable.
The hosts are totally hands off. Check in and check out is done through a code and all communication is done via messages.
Do note that check out is 10 AM and factor this in your travel plans.
A request for a later check-out was not accommodated even though there were no guests booked for check in that day. I do understand it is a business, and the hosts said would like to clean the place immediately, in case of a same day booking.
However, we would have appreciated accommodating our luggage for a few hours since we had to be out of the apartment by 10am. Our train was departing at 2:30 pm and the host did not reply/denied our request to keep our luggage. Our long onward journey started too early on the streets of Porto dragging our luggage around for many hours.
Also, take a picture of where you leave the keys when you self check out, and send it to the host. We left the keys on the key rack which we thought was the ideal place, but the host was messaging that the housekeeper could not find the keys. I was concerned that I will be charged for replacing the keys if it was not found but relieved that they did find it.
