Claudio's place is awesome ! The apartment is bright, with enough space for the 3 of us, the kitchen is fully equipped, the neighbourhood is quiet and safe, the underground stop (Mariatorget) is just a 2 minute walk from the apartment and it takes you to T-Centralen in 5 minutes. Communication with Claudio (and his son Nikita) ran smoothly and they answered to any question in a few minutes.
Highly recommended to everyone who wants to spend some days in the heart of Stockholm !
