Stayed here for two nights with my girlfriend over the weekend (Fri & Sat). We arrived around 6pm on the Friday; we weren't able to confirm the exact time until the Friday but Louise was very accommodating and quick to reply.
The place itself is wonderful! It's a converted barn but don't assume it's small - there's plenty of space/rooms. The main lounge/kitcken/dining area has everything you need (including a gas hob and cooker if you want to cook). There is a large bathroom with a separate toilet. Also a little private outside area/courtyard allowing you to sit outside. Upstares is a large bedroom (plenty of space, it almost covers two rooms).
There were electric/gas heaters in the main rooms which was much welcomed/needed (it was chilly!). I imagine it might get a little toasty in summer without AC.
The barn is on same property/plot as the main house, which we liked as it felt quite secure while not losing any privacy. Two adorable dogs were often chilling outside - very friendly! There is on-street parking that is unrestricted/free over the weekend (from late Friday afternoon) which we made use of, unsure where you would park otherwise.
Town was about a 20 minute walk, bit more over to Salamanca market. About a 10/15 minute walk to Elizabeth St which has some decent bars/pubs for the walk into town (be sure to try the New Sydney Hotel!) Airport was a 15 minute drive.
Only possible downside (for some people) is the stairs leading up to the bedroom are very narrow/steep and the ones down to the bathroom a bit awkward - so I'd perhaps think twice if your mobility isn't great.
Overall we had a great stay and would thoroughly recommend Louise's place - would return!
