Great space, very clean and perfect location close to tourist attractions. However, no air conditioning in the apartment meant that windows had to be opened at night as it could get quite warm. As a result of this we were usually woken up quite early due to the street being very noisy. Not ideal.
Upon checking out we were advised to leave keys inside the apartment. Unbeknown to us the main door (usually unlocked from the inside) had been locked. Without a key to unlock it we were trapped in the foyer at 6am for nearly an HOUR whilst trying to get a hold of the host and neighbours to let us out so we could catch our flight back home. Totally unacceptable for this to happen. Whilst this slightly soured the end of our holiday, our experience in Prague overall was a positive one.
