One of the only things I could say I disliked is the lack of a common area or space to interact with other guests. There are seats downstairs and on the second floor landing, but there isn't an organized "lounge" area. The breakfast room is set up simply for breakfast and otherwise sits empty. This isn't make-it-or-break-it for me.
Secondly, I couldn't see if there was a "Do Not Disturb" sign for the door. I would have liked this when I was sleeping in or did not require maid service as I was dawdling in the room that morning. It wasn't that disturbing in the morning but it would be easier for guest and staff to know if someone is still in the room during servicing times.
One note for someone using the superior single -- the window is very tall and large. This means that the cold will get through which means sitting on the bed without a blanket around your shoulders gets brisk. If you are prone to being cold often, try the other single room or ask for more blankets!
Firstly, I loved the location. I originally thought I would enjoy Windermere more, but it turned out I loved Bowness, what with the lake views and the shops and restaurants. Having a guest house in Windermere would have made walking around Bowness tough (Windermere is on a hill and Bowness is down by the lake) but Rosemount is right in between the two towns. This meant I could explore both without walking too far away from my Guest House.
I also loved the complimentary spa pass you get when staying 2+ nights. I definitely recommend taking advantage of this, with lake views right from the spa pool! It was refreshing and definitely filled up my time on the winter rainy days where going out for extended periods of time would be tough.
I stayed a total of 5 nights in the superior single and I didn't want to leave. The room was small but had every amenity. I ate breakfast (since it is served between 8:30-9:30) only twice, but it was delicious. I only skipped it because I wanted to sleep in!
Andrew and Louise were very helpful but also not the type to linger around. They would respond very quickly if you rang the doorbell to ask questions or for information but were not seen around otherwise (unless in the mornings, where they would check in on those eating breakfast). I like this hands-off approach, where the hosts are accessible, but not overbearing.
A small DVD collection if you want to curl up with a good movie is available and the rooms are heated well, as I went in winter. The tea tray was sufficient and each time I had my room serviced I was given another little treat.
