We went to Prague as a small family: my partner, our daughter (1 1/2 years), and me. The apartment was great for that. So close to all the sights, we could simply walk with the buggy. The apartment was spotlessly clean and had an extra room where our daughter could sleep while we sat and enjoyed a quiet evening. The living room is quite spacious so that we could relax after a long walk around the city while our daughter had enough room for playing and running around.
The kitchen is equipped with everything one could ask for, even if you stay there longer and want to cook your own meals (spices, oil, etc.). Even tea and coffee are provided.
There are also many things specifically for guests with children - a small bathtub, plastic cutlery, bowls, and plates, a washing machine (god knows parents need this sometimes!), a crib, ... ... As a parent you really appreciate this (it was not at all expected) and this made us feel really welcome.
The breakfast was delicious. It was so much you could easily eat two days from it and/or take something on your walk through Prague.
Lastly, we got some great tips on where to go and what to visit in Prague from our host and the guidebooks provided are indeed quite useful.
Thank you for a great stay - we'll be back!
