Laura and Shimon's "studio" guest house is spacious and clean. It has everything you'd expect and then some (full-size pool table, anyone?), in a great Parkland location just off 441. It's on a very quiet dead-end street with large homes and almost no traffic. The hosts are lovely people, and were very responsive with communications and requests.
The guest house is fully detached from the family's residence on the property, so you'll have plenty of privacy. Walk in/out from the level of the driveway and patio, no stairs at all. Note, however, that the use of the word "studio" means that the entire space is a single large room (of course the bathroom is separate, with a very nice shower enclosure but no bathtub). Guest couples/families where some go to bed earlier than others, please be aware. There's a LOT more space than any hotel room I've ever been in, but it's all shared space inside.
Thanks again Laura and Shimon!
