1879 National Historic Landmark – Suite e cucina di lusso nel boutique hotel vittoriano sulla spiaggia

Each floor had some little problems, that when changed became very good attributes.
The left one has a separate room. No need for that. It is a small space so no need for further dividing it. An open space with a nice modern kitchen will be better and give more room.
The middle one mad a problem with sharing the bathroom/kitchen part. There is no need to do that since it becames too compact. Having a bigger toilet with a spa is better. And the kitchen has a better place. To enjoy cooking.
The right one did not have a good enough kitchen. Too much focus had been placed on the pipes. Having the kitchen on one side and the toilet a little moved up is much better. That way there is more space.
There are example renders how the space should look like. 
Since you are going to buy alot of furniture ( many rooms, it is a hotel ) you can never know what peices you can get. Sometimes you will get a pretty nice discount for such a big buy. So that is left up to you.
