On holiday
How is it so far? What's the weather like?
Having a great time! We are in London and although it was raining yesterday at the start and during the afternoon we weren't really affected because we'd decided to do to the natural history museum. The kids were super excited about being on holiday that the addition of the brollies wasn't an issue (I guess at 6 and 3 they are used to the English weather?!) 
Describe your accommodation eg the amount of space, outdoor area, particular parts of the house
We are in a 2bed apt. Spacious enough for 4 of us. One twin, and one double. One ensuite and one other. All mod cons, so there was no need to bring anything other than breakfast stuff. Kitchen well equipped, ton of dish washing tablets, balconies where we've enjoyed breakfast to morning with the morning sun.
There is also an underground parking for cars (which we had) and a concierge at the reception. Feels all very safe.
What else are you doing outside of the housetrip stay, in the local area?
We've done a trip to the natural history museum yesterday, local tube was 10min walk away along a very picturesque walk by the Thames. Also went to the lady Diana play park which was a fantastic park right in the middle of London. The kids might have liked it as much as the dinosaurs?!!
Intend to go to the aquarium today, and Greenwich tomorrow.
How does this compare to previous hotel holidays or previous home rental holidays you've experienced?
We've gone on farm cottage holidays before and it's similar in that you have the run of the place for however long you've booked it. Difference obviously in that on the farm, you do farm/countryside stuff and being in London you feel that you've got to make the best of it, and go out and see the sights, museums, etc. and of course, of the farm you drive around the area, London you go on the tube (which is very expensive!!).
What have you got up to at your housetrip property?
The first night, we brought a takeaway from sainsburys for us, and kids had a pizza. Which was a sound choice. Showers and sleep. Second day we had breakfast, then went out. Had dinner out so came back again to just showers and sleep. Today, we've just had breakfast and the kids are playing in the sun on the balcony. Will go out in a bit.
Have you used the kitchen to cook at home? Where did you get cooking ingredients? If you haven't been cooking much, how often did you choose to eat out?
We haven't really used the kitchen for anything beyond heating up the takeaways, and breakfast stuff. Reason being we made the decision when we got this trip to London that we wanted to take advantage of all the amazing food here in London. So last night we had a fab dinner at a Chinese restaurant that we knew about. I imagine tonight we will do something similar.
What have your dc enjoyed most about the housetrip experience? And have you/your dh enjoyed most?
The children have enjoyed everything... From TV, showers (we have a shower over the bath at home so a stand alone shower is a novelty!). Dh enjoys the nearness to the Thames and river things, we are in zone 2 and it's just really nice to be in London and at the natural history museum (eg) for before it opens up at 10! We live an hour-ish away from London and even with the best of wills, with the trains coming once an hour, the earliest we get into London for anything (with kids) is nearer lunch time.
