Thank you for your feedback. This apartment has 80 m2. Usually there is staying 8 people and nobody complained that there is no space for them so this point is individual. You can see the size of bedrooms on photos. We will check the apartment and we will try to find small maintenance problems. It is better to contact us immediately if you have any problem in the apartment and we can fix it as soon as possible.
Thank you for your review.
The apartment is non-smoking. We do our best to warn guests not to smoke in the apartment.
Thank you for the information about balcony door. We will check it and fix it if necessary.
The check-in is not in the apartment but in the check-in office. This information is mentioned in the description of the apartment.
The neighborhood is perfect as you mentioned so I hope that you enjoyed your stay in London and you will come back again.
