3 of us stayed in David's hostel and had a great time. The rooms are very spacious and each room has it's own bathroom which was a welcome surprise after staying in other hostels. The location is good as everything in Berlin is easily accessible by public transport from the hostel. There is a bus 200m away that takes about 15-20 minutes to get into the city centre. There is also a tram that runs every 5 minutes so it's very easy to see all of Berlin. David is a great host and and I definitely recommend staying here.
