It is located so close to a metro station that the subway runs under the building. Literally.
We did not get the room we booked previously. We got one with the same conditions, but that latter one was more noisy. We got all the information we asked for about the city, but it was far from a guest friendly approach.
It is pointless making guests a(n int`l) phone call to be let inside the building when there is a door phone at the entrance door of the building (the guesthouse is located on the ground floor of a block of flats)
