I want first to say that Gisela and Bastian are very very nice, friendly and welcoming people. It was no problem at all to get all the information which was important before arrival, and it was completely comfortable after we arrived. Everything was so well prepared, also a welcome beer and snacks were waiting for us :-). The apartment is absolutely amazing, very comfortable, with all the necessary equipment and small but nice garden. All the telephone numbers which we could need were provided, the tube map was also prepared for us! During our stay Gisela came to see us, and brought again some beer :-) recommended nice places for dinner and helped with all the questions which appeared by that moment.
I highly recommend this apartment, and it is a big pleasure to meet such people and be hosted by them!
