This place is clean, in a good location (central to Balboa park and downtown San Diego area) and very large. Frank was extremely responsive to any questions that came up. So many helpful guides for what to do in the area were provided in the unit.
Please note that there are two flights of stairs to get up to the unit and the coin/app operated laundry is on the ground level. It's also an older unit so the kitchen is small and there are some quirks. If you stay in the hotter months the AC can take some time to cool off the place.
Overall a great stay, but do be aware of the stairs and hills in the area if you're planning to be on foot!
