"Geros atostogos. Patiko išlikusi senoji pastato dvasia: pastatas, žaluma ir iguanos prie baseino,"

8.0

Jaukus baseinas ir aplinka prie jo, maloni muzika, ramybė. Labai patiko iguanos prie baseino, valgančios nukritusius žiedlapius ir pozuojančios visai noriai.

Santechnika, plastiko naudojimas per pusryčius. Kodėl negalima bent jau puodelių "tikrų"?
