I had an incredible time at Lola's place. It was a block away from the Stadmitte U-Bahn and right smack in the middle of everything (few blocks away from Checkpoint Charlie).
Room was small but sufficient and had its own bathroom outside. Both were spotless.
Lola is also a great host. Open communication and very friendly! When I finally met her it felt like we knew each for a long time! She also let me drop my luggage early with no extra charge. I also had an item that I ordered and she let me have thw Berlin-based merchant send it to her so that it would be there when I arrived.
All in all, perfect experience. Will come back soon!
