We enjoyed our stay at Ana Cristina's and found the location worked well for our exploration of Porto. It was very clean and had what we needed for a good stay. It offers a large space with good seating and storage. They have a nice website with tips on places to eat. We really enjoyed lunch at Las Caracas. There are local restaurants close by also. They helped us check in early and were quick to answer any questions beforehand. We appreciated the savings on the airport shuttle that they set up for us. A couple of things to note, we were there in March with temps in the 30's at night and found the little heater couldn't do much for warmth as there is no central heating. There is a fairly steep staircase to the apartment with no handrail. If we return to Porto in warmer weather, we'd certainly like to stay there again.
