"The Flat" is a lovely space in Tekapo. We got to meet one of the hosts who was very warm and welcoming to us.
There is a separate "sitting room" attached to the bedroom and you walk out into a common entry way area to your private bathroom. I think for most people the preference is for an en suite bathroom, but it wasn't a problem for us.
Their previous microwave broke down right before we got there, and they made sure they put the brand new one in for us. We didn't get a chance to use it, but I thought it was very kind of them to make a point to get it in the room quickly in case we needed it.
The location is terrific, just a quick 2 minute drive to the cafes and restaurants in Tekapo.
I would stay here again without hesitation!
