"Life up here is absolutely spectacular," he said via video-link to the journalists gathered on solid ground, showing his not-so perfect weightless-conquering skills with a not so perfect back-flip.
"Practise makes perfect. Give me another week," he laughed.
Peake has a very busy schedule ahead of his, both with the science programme and the visiting vehicles.
"That is taking a lot of time to unpack that. Preparations for potential space walks are ongoing. And of course with the future space X-vehicle that come up, there will be even more science onboard that, too. So, plenty of work to do over the next 6 months."
Peake almost struggled for words when asked to describe his journey.
"It is actually really hard to describe, I mean just the whole ride into space on the Soyuz rocket, what a phenomenal machine! So powerful, such a smooth launch, and the the arrival onboard the international Space Station. And adapting to this weightless environment. I'll be able to go to the cupola and look at that amazing view of planet earth. It's way beyond my expectations."
And he added that the blackness of space was the most unexpected.
"I mean it's the blackest black. And you realize just how small the earth is in that blackness. And that was a real surprise to me."
Peake blasted off to the ISS with a Soyuz spacecraft on December 15 that also successfully delivered a Russian and an American to the ISS.
The otherwise smooth journey ended with a slightly delayed docking at 1733 GMT as Russian commander Yuri Malenchenko aborted the automatic procedure and manually guided the spacecraft towards the station.
Alongside Malenchenko, a veteran of long-duration space flights who is on his fourth space mission, were NASA astronaut Tim Kopra and Peake, both former Apache military helicopter pilots.
Peake, 43, is a former army major who is on a six-month mission for the European Space Agency (ESA), and became the first astronaut representing the British government and wearing a Union Jack flag on his arm. The first Briton in space was Helen Sharman, who travelled on a Soviet spacecraft for eight days in 1991.
