We had a great time at Andreas place, it is very pretty, very clean et and very good equipment in the kitchen.
The apartment is very well located next to several bus stations, some minutes walking from metro station and next to some very nice markets.
The communication with Andreas was very easy and the answers were very quick. He also proposed us to check in early and to check out late if necessary, which was so great and helped us enjoy our last day in London.
I definitely recommend this place.
