We booked Lenka's place for a weekend trip to Prague for 10 people, each of the bedrooms had two beds, and each contained a sink and an air cooler which was extremely useful. The apartment is huge and with 10 people it was extremely useful to have two separate showers and two separate toilets. It's also super centrally located, we were no more than a 15 minute walk from many of the major attractions in Prague.
The hosts were even able to organise taxi's for us to and from the airport - this was invaluable and meant we didn't waste any time and the cost of the cabs was very reasonable.
Our check-in was very smooth, we were given some great suggestions of places to go, as well as how everything in the house worked (including the awesome coffee machine!) - the host also waited up until 1am as our flight was delayed, and they didn't complain and were extremely friendly.
If you have a trip for a large group in Prague, you couldn't ask for a better location, or value for money.
