In Gaelic, "of" is signified by the relative placement of nouns. The first noun is possessed by the noun that follows it. "place peace and happiness" in Gaelic, however, would mean "place that belongs to peace and happiness". You'd be better sticking to a noun and two adjectives.
To describe a location, or any other inanimate object, as peaceful, and certainly to describe it as happy, is to personify it, and it may not be safe to assume this will make sense in another language, which may be more literal.
In any case, you can try "àite sìtheil agus toilichte" ("place/location peaceful and happy/pleased").
It should be noted that no word needs to be added to a noun, in Gaelic, to signify "a" or "an". Consequently, "àite" can mean "place", or "a place". Seeing the above phrase, a Gael might assume it to mean "a peaceful and happy place".
