Located in Neustrelitz, Germany, it's part of a tiny home hotel called Slube, which designs minimal concrete "Slubes" for up to two people, according to its website.

There are three types of Slubes: Basic, which is one story; Home, which is two stories; and Tower, which adds a rooftop terrace. I booked a Home Slube.

It was 16 feet tall with two floors totaling 106 square feet.

When I arrived by train from the airport in Berlin, there didn't seem to be any employees on the property. But an email from Slube informed me I'd be staying in room five and could check in by myself.

In the sitting area, there was a table that folded in to save space when not in use.

Beneath the benches, there was enough space for me to store my luggage.

I stored all of my clothing and toiletries on the first floor.

I was impressed by the amenities packed into such a small room.

There was a curtain separating the shower head and sink from the toilet and storage space.

The windows on the first floor had a film over most of the glass, which allowed me to let natural light in without sacrificing my privacy.

I thought it was easy to climb but could be challenging for some.

Knowing I was securely fastened into the bed area made falling sleeping easier.

On the floor was a full-size bed that I found comfortable. I thought the pillows had the ideal ratio of fluff to firmness for my neck and head.

Before bed, I watched some of my favorite shows.

It had easily accessible outlets, a pocket for the TV remote, and more space for my electronics and water bottle.

It had a black-out curtain for privacy and early morning light.

I controlled the lights and temperature of each story from my phone.

While I can't stick a second story into my own rental, the European tiny home still gave me inspiration for how I could make better use of my space, starting with vertical storage hacks.
