I didn't meet Thomas in person because i arrived during christmas period so he might be busy that time. However Thomas is very quick in reply to my question and he also ensure we are able to enter the house. The house is clean and spacious for 4 of us. There is a double bed and one big sofa which can be transform into a double bed too! The location is nearby to the bus station and it is very easy to access to all other tourist attraction. Overall it is a pleasant stay and will definately come back to Thomas the next time I visit Berlin again!
