I didn't meet Ivy but the communication was very good. The room is large with access in the garden. There are two bathrooms with all you need. The kitchen has a lot of electrical devices in order to prepare or store your food. I didn't use any of them but some of other guest did.
The neighborhood is beautiful with identical style buildings but each neighbor gave a personalized look.
The acces to Gants Hill tube station is at 10 minute of walk through a beautifull English area.
I will definitely stay in the same location in my next trip to London.
