We had a lovely stay at Lukasz's place. Lukasz is a great host. The communication was super, he is very friendly and helpful. He even let us stay a little bit longer, when our flight home was later.
The price/quality ratio is great. The apartment has all the essentials you would need.
The apartment is in walking distance from a lot of tourist attractions, like the Royal Mile, Carlton Hill and the City Centre.
We would definitely recommend staying at Lukasz's.
