Magdalena was really good about reaching out to us in advance, prior to our stay to let us know the directions and to ask if we had any questions. We loved the location -- very central and convenient, and the apartment itself was spacious enough for my friend and I. The decor was as cute as it is in the pictures, and the bed was quite comfy.
There were a couple things we were disappointed about. Firstly, it appeared that the sheets were not changed prior to our arrival, as there were many hairs on the sheets. Secondly, the bathroom door handle was in bad shape. At one point, it didn't work and one of us almost got stuck in the bathroom.
With a few minor adjustments (making sure the maid cleans properly, new door handle), we recommend this apartment if you're staying in Prague.
