We stayed there with 4 adults during a week in july. Everything (and even more) was provided as described. There's one bedroom but also a sofa which can be transformed into a bed, and it's a good bed. The garden gives the possibility to sit back and to relax after a day of sightseeing in Edinburgh.
It's also a quiet neighbourhood about 20 minutes (5 minutes’ walk to the bus station and 15 minutes ride) from the Center of Edinburgh. There's a supermarket (8 minutes’ walk) nearby and also a few good restaurants (cheaper than in the city). But if you have questions, want any advice or more information, contact Fiona and Olaf who are always ready to help and they respect your privacy even if the garden is common. They did a wonderful job by transforming the former recording studio of the Bay City Rollers to a very cosy place to stay and the are the perfect hosts to !
