German is more reluctant in its use of lieben (“to love”) than is English, particularly in reference to things. Such phrases as “Ich liebe den Teppich in deinem Zimmer!” (“I love the carpet in your room!”) are a typical feature of “dubbing German”, i.e. literal translations from English as commonly found in dubbed films or sitcoms. A more native way of expressing the same in German would be “Der Teppich in deinem Zimmer sieht super aus!”, or “Der Teppich in deinem Zimmer gefällt mir sehr gut!”, or something along these lines.
Even among people, lieben may have a somewhat solemn sound. A more normal way of expressing “to love” in spoken German is lieb haben, particulary among friends and family, but usually also between lovers. (See the latter lemma for more.)
