My 2 weeks stay at Matthew's place was very good. The house is well located and connected,very easy to access any bus/train station. The Lewisham area seems to be rough yet interesting to experience. I don't have the impression that it's unsafe.
I had a double room on the roof floor which contains separate toilette. It's very quite and has the privacy I need. The interior is very nice and the bed is comfortable. The whole haus is clear and tidy. Matthew was very helpful with everything. Not just he provided useful informations about London and the Maps and route advices but also with other personal things like printed my ticket or documents etc.
The Kitchen is not accessible for cooking. But since I don't really have to cook during my stay, it dosen't really matter to me.
I will recommend this place.
