To start with the positive: The essentials work well - air condition, big fridge, water in the shower (don't forget a needle, if your not Italian, as almost everywhere :-). The terrace in front of the app. nicely decorated and always shodowed. The nearby beach is really wonderful.
The following might be judged from different points of view - romantic, typical or just scruffy: paint coming from the walls, unfixed switch plugs, all cranes spelling water everywhere, water coming in from the roof with heavy rainfall, every shelf covered with "decoration" as stones. mussels, empty bottles and such, a table really sticky from age, mold in the shower....
What was annoying: The "stairway" to the appartment is extremely narrow an steep, even for Gallipoli. The picture showing the steps to the "laundry terrace" - these are not so steep as those you have to go to the appartment. We are accustomed to living up high, but those steps, escpecially with luggage or some bottles of wine kept challenging. This should be mentioned in the text - for people who are not in their twenties the appartment is unconfortable if you stay there longer.
The pictures of the roof terrace are misleading: You would need to carry up chairs and food two further stories to eat or drink there, the picture with the seafood shows the neighbor's terrace that is neatly furnished. The roof terrace has no shadow during daytime (which you can see) and no light by night.
The appartment is quite clean at the first look, but whenever you move something, you find dirt, spider webs... Most of the kitchen stuff had to be cleaned before using.
All in all: If you want to spend some days at Gallipoli with a main focus on going out: The place is charming. For a longer stay: definitely no.
