I stayed in Caren's house for 4 nights 5 days. Fitst of all the house really cozy and comfortable. Grunewald is near a forest so there is really fresh air around. I slept really well and Caren prepared desk with papers, pen, post-it where you can organize your trip. I also apreciated the tee bolier and coffee machin for the breakfast (there is a Bakery and supermarket nearby where you can buy fresh fruit and food). The towers in bathroom had really great smell. I loved also two cute cats that you can see sometimes on the garden :) I really enjoyed this experince. Thank you again to Caren!
