I stayed with my friends (6 people altogether) in Bernardo's flat for 3 nights. He was available for us any time, and provided all the necessary help. The flat is cozy and well equipped (as in the description), including pocket tourist guides, which is so nice :) The flat is located conveniently, near shops, restaurants and S-Bahn stations. Recommended! Thanks, Bernardo, and good luck in the New Year!
