I stayed a couple of days with my boyfriend in this apt in Prague as a part of a longer trip around Europe. We had an amazing time! Everything was even better than we had expected.
The building looks more like a hotel, with receptionist and all (One of them is Sophie, super cute, friendly and attentive; she helped us with everything). The apt itself is huge! Super clean and with everything you may need. They even clean your place every day!
Overall it was a wonderful experience and I will recommend it to anyone who is travelling to Prague
