I put a lot of effort into making the beds comfortable and attractive. I bought the thickest mattress toppers I could and since then, guests always comment on how comfortable the beds are. I also dress them nicely with bedlinens coordinating with each room's decor. I think random bedlinen can really bring down the look of a room, but if in doubt, it's easiest to go for something plain and neutral. I also choose matching towels.
One of the most popular elements is the welcome chalk board with each guest's name written on it. Most people jusst love that personal touch. I also include a letter rack with maps and leaflets, magazines in different languages, a carafe of water and glasses, hairdryer, travel size toiletries and practical stuff like nail files and sewing kits, travel adaptors and plenty of hangers. I tried bowls of fruit for a while, but the fruit would usually end up being thrown away.
In terms of the decor, each of my rooms is different but all of them have been decorated with love and attention to detail, which is something that many guests comment on. Nothing in them looks random, but I also don't go for everything matching either. I guess you could say the furnishings are eclectic but coordinating. It's important to have at least one mirror, for practical reasons but also to increase the light and sense of space. I try to avoid the tempation of using cupboards and drawers to store my own stuff and leave everything empty for guests, excpet bookcases, which should be filled with books.
I would like my guests to feel a bit special when they stay in one of my bedrooms, not just that it is a basic place to crash. Sure, many of them will be out and about most of the time, but it doesn't hurt to have somewhere nice to come back to.
