Even though we had a satisfying stay at Shaz's flat, there are a few things that need to be said about it.
Good points : Clear informations about the appartment, located in an animated neighbourhood with nice pubs and good restaurants. Bed, furniture, towels and so on were good.
Bad points : First. One must know that the appartment's windows are single-glazed, and overlook a very noisy and busy street. Thus, from 8 P.M. to midnight, it is absolutely impossible to sleep, because of the klaxons, the braking-sounds, the sirens of police cars, and drunk people having a beer outside the pub.
Second. We tried to reach our host twice, to ask a question about our luggage, at the end of our journey in London. He never answered our text messages and on the AirBnB email box, we only got automatic messages. Do not hope any further information from the host...
This being said, I guess we did the right choice by choosing this location, because it is very hard to find in London such a correct quality/price ratio.
