As for the sky, the chances to see a cloud over the Iberotel Apulia in Summer are very, very little. The chance of a rainy day is zero, because Salento is a dry land. One does not need to check weather forecasts, because any day is basically as sunny as the earlier one (if your skin tone or that of your child is light, think about protection factor 50).
As for the sea, Iberotel Apulia is situated at walking distance from the long, shallow, and clean sand beach between Gallipoli and Santa Maria di Leuca, which is orientated from NW to SE and is therefore protected from the local dominant Summer breezes, mostly veering from N to W. This makes it a very safe and pleasurable place for swimming, especially for children (at dawn and sunset, the sea might be as still and clear as a swimming pool).
As for the land, the Iberotel Apulia is inside a protected natural park, which develops from the sea dunes, to the reeds and Mediterranean vegetation, to the Aleppo pine trees, and finally to the lawn around the swimming pools and the courtyards (one may practice in privacy jogging or yoga or the like).
In such great natural context, the large and harmonious swimming pools are the heart of the hotel. From there, one may reach the beach-house to take a drink and spend time on the beach, or the children playground under the pine trees, or the mini-club for children activities, or the scout base (yes, there is one), or the bar, or the restaurant, or the fitness and wellness center, or the sport courts, or the shadow of the olive trees. At evening, one may enjoy live music by the swimming pools or attend the show at the amphitheater (there is one every day).
No more, no less, the air-conditioned rooms and the service are according to seaside southern European 4-star hotel standards. The 'all-inclusive' formula is a successful one, in that one takes in abundance what one wishes at breakfast, lunch, and dinner. The personnel and especially the animation team energetically attempt to make everybody feel at ease, and mostly succeed.
You may reach the Iberotel Apulia from Brindisi airport (ask the reception for a shuttle bus), get there, and just take it easy. I was there with my little family, and we had a splendid time for three weeks in a row. Around the pools or at the restaurant, we met families from the US, from Germany, from Belgium, from France, and most of all from a variety of places in Italy. My child (6 years old) asked me whether we could stay again at the Iberotel Apulia next year, and I replied that we will indeed think about it. This says it all.
