Two magazines recently listed the best cities to live in. Here are two of the cities listed as “the world’s best.”

SAN JOSE, COSTA RICA  The city has comfortable weather all year round (15°C to 26°C ). Housing is not very expensive in San Jose. Also, many of the city’s older neighborhoods are very beautiful and have small hotels and cafés(咖啡馆). Beautiful mountains are around the city. You can visit them easily from San Jose.
