I love a good game. I leave a shelf full for my guests - I try and have things that will suit all ages. A deck of cards, dominoes, chess, draughts, and ludo are staples, but I add in a few silly games too such as Kaplunk (a great game where you take it in turns to pull sticks from the tower without letting all of the marbles drop), oh I have Jenga and Pictionary too!
I also have a few large garden games - a giant connect4 and a giant Jenga (can you tell I love Jenga)?!
I like adding a few special touches to make my guests feel at home. I have books, jigsaws, and a craft box too - if the weather is poor or guests fancy a relaxed day in I think it's nice to have things to hand they will appreciate.
One of my properties is in a really family friendly area and close to some good attractions - so I'm making that place as kid friendly as possible. I've included toddler toys and playmats etc there plus useful equipment e.g. highchair, cot, stairgates etc. I don't have kids so I asked about to see what parents might like to see for their little one's - I found this useful too if anyone is interested:

Anyway have fun and happy hosting!
