Alberto is a great host. He gave me perfect directions to his house; it was very easy to find the flat from the train station. The location of the flat is superb; very easy to reach city centre by walk or by public transportation and it is very well connected with the most important sightseeing spot of the city. Alberto is very friendly and always available to help with suggestions about restaurants, bars, things to see, airport connections, etc. I am glad about my choice. Enjoy Oslo :-)
