Tino's place is more than you expect. If you are browsing through the website and not sure yet. I have to say you don't have to look any further. I will break it down in different categories.
Location= very central, across the street from shopping malls and grocery store. You don't walk more than 2 min to buy anything you need. Train stations across the street which can get you in Berlin anywhere. It is 10 min walk from all major tourist attractions. You can't beat this location.
Cleanliness= The apartment is very clean at all times. They have weekly professional cleaning done and both guys keep the place very clean.
Safety= I was a bit anxious when I was booking this, but the guys are incredible. I never lived with two males before but I felt always safe during my stay.
Communication= Both guys are very good at communicating and respond back fast. Even if you have any questions related to the city they are great resource.
Overall, I would stay here again. This place had all the conveniences I needed for my stay. I was doing work abroad and I needed all my luxuries I have in the U.S. and it exceeded it for sure. Thank you again for your great place and kindness.
