Thanks Terence, it was great having you and your family with us and appreciate the nice comments - a couple of things to clarify, the 4th floor no lift is clearly indicated on the property description (and I also check that before confirming the booking request) and so is the fact that there is only one bathroom in the property so hopefully this should come to no surprise to anyone and these are some of the reasons for the more reasonable price asked for a 3 bedroom property in Kensington that would normally go for a much higher price.
As for the shower, I'd say we never had these issues before with 6 people staying as the system has high capacity and should not require any wait in between showers unless the showers are particularly long but I lived there myself with other 5 people and we never had any such issue. thanks again and I wish you and your family a safe journey back home, cheers
Thanks Eduardo for the nice comments, the building next door is going under general maintenance & repair (so not really a 'hard' renovation but more a clean up and re-pointing of bricks). The works are due to be completed in August and always progressed during daytime (and not on the weekend). Being the adjacent building here in question, little was known to us on their plans but in general this is never been felts an issue by the locals as every building in the area needs to do these works every 6-7 years to keep the buildings in good state of repair and normally not very noisy works as not structural.
