Ondrej's space is beautiful and comfortable for our group of two couples. He was willing to store luggage, add a night when requested, provided fans during the unseasonably hot weather in Prague, and provided detailed information about things to do and see in the city. The Baroque building is lovingly decorated to honor the space and below on the first floor, the restaurant Style & Interior had the most delicious and beautifully presented food, that surpassed anything that I had in Prague during my 3 weeks there. I would definitely stay there again.
It is located on a very busy street, with tram stops, which makes it a great place to use public transportation and that is top notch in Prague. But, does make it challenging to get an uber or bolt at the apartment address. We were able to get dropped off there, but had to walk to an intersection nearby to get picked up to go to the airport. Probably should have used public transport to get there, but didn't manage our time well enough to do that.
