Once you've ascertained where to stay on the coast, it's easy to calculate how much it costs to stay in Galippoli for two.
Let's take a standard holiday for two in the seasonal month of July. So, on average, at such a time you should count on accommodation in Galippoli at a price of 700 EUR. Depending on the season and accommodation options, this amount may vary slightly.
For example, if you are looking for cheap accommodation in Galipolli, then you should consider a 3-star hotel. A 7-night stay there will cost 595-655 EUR for two people. 4-star apartments will cost more in the area of 800-900 EUR. A holiday in Galippoli in the old part of the city, closer to the centre, will cost about the same amount.
