We really enjoyed Magnus flat, believe me when I say that it even looks better than the pictures.. We were a young couple with our very cute 5 months old baby. We got to the flat at night, finding Magnus's agent waiting for us to guide us through the apartment. We found a very well decorated flat, and fully equipped (sparkling wine in the fridge, towels, blankets and sheets, and even toothbrushes and deodorant in case someone forgot to bring it with him. The kitchen is well equipped, we used it every night to make dinner.
And finally - the excellent location - 5 walking minutes (with a baby stroller) to Charles bridge, Wenceslas square and the old city.
We recommend this flat to everyone. We will come here again for sure next time we are in Prague.
