The Thalia Hotel is beautiful located on Narodni street, very close to the old city centre and on the other side 150 meter from the Moldau river. Most of the staff members are very young, they look like trainees from a hotel school but they are friendly and helpfull. The breakfast is outstanding. The building itself has a nice atmosphere. The rooms are fine, however, the beds are just too short. Besides that, it is rather poor for a 5-star hotel that you have to stand in the bathtub when you want to take a shower.
Prague is a great city and we surely will come back, however, the Thalia must provide some larger beds, otherwise a good sleep is not guaranteed.
