Short version : Sabina and Yoav are simply great hosts. You won't regret staying with them. The apartment is exactly as described - clean, stylish, comfortable. The two are very helpful, if needed (tips, recommandations etc.) but will always respect your privacy.
I stayed for one month at Sabina's and Yoav's apartment and can highly recommend it. The room has everything you need: Even a small kitchen including a huge fridge. The bed is comfortable and the shower is amazing. Everytime I had a question or needed recommandations Sabina and Yoav were there to help. Regarding the neighborhood: Oservatory is a good and safe place to stay during your trip. It's a student district with lots of different shops and bars just around the corner. (Even a lot of vegan options).
