We spent two nights in Carlos apartment in Grünerløkka. The apartment was exactly as described and properly cleaned when we arrived. Carlos was friendly, always smiling and service-minded. Communication with Carlos was a breeze, as he always replied to our messages within minutes. Grünerløkka is a great place to stay. It's very close to the city center, and it offers a variety of cultural experiences, as well as a lot of great restaurants and nice bars. It suits young travelers as well as families. We can highly recommend Carlos' apartment to anyone.
