We stayed for four nights in Stockholm at Ami and Jonny's place even though we originally planned three nights. Their apartment is located in Södermalm, which is one of the hippest spots in the city and a perfect starting point for exploring the rest of Stockholm. Directly opposite is the subway station Mariatorget, but you can also walk through Gamla Stan to the newer parts of the city and the harbour, which is what we did.
The apartment was very clean and comfortable while the breakfast prepared by Ami was just the sweetest thing. She really is a great host and we look forward to return in the future.
