Hotela Panorama Vigo 

If I would have been traveling alone- my choice would be probably different: I'd vote for a room in Bulgarian traditional house somewhere in the Old Town. But my little son loved Panorama because it's located in the green park over the sea, with many playgrounds, 5 minutes walk to fun, fresh, and friendly South Beach cafe - my son's favorite for lunch, 5 minutes walk to perfectly clean beaches, and 7 minutes walk to the Old Town - the main attraction for a curious and hungry for new adventures young mind. And - the greatest perk of Panorama Vigo - the swimming pools:) As Herodotus wrote about Black Sea that the Ancient Greeks settled around it as frogs around the pond, so the kids around all three hotel's outdoor swimming pools. Now some minuses: the apartments overlooking backstreet are noisy at night but at the same time they are in a shade all day which is great during hot summer days. I highly recommend to choose apartments over hotel rooms, this way you can always have your own breakfast at your convenient time not depending on hotel arrangements, and more privacy. Also, don't necessary look for sea view apartment: the backstreet rooms get you some really fresh air from the mountains in the early morning (and also give a pick on the sea! just from another side).
