The Hotel Inturprag is about five subway stops from the centre of Prague, in what seems to be a mixed residential/light commercial area.
The metro travel was no problem, trains are efficient, clean and frequent. It's not as nice as staying in the centre of Prague, but then, for what you get it's nowhere near as expensive.
Main issue was finding the hotel. Here's how: When you come to the top of the escalator from the Ceskomorovska Metro stop, turn Rt. Walk out across the area where the buses come in. - towards the big O2 sports stadium. When you get to the street proper (Ocelarska St), turn left.
You will see several ochre, teracotta, rust coloured etc buildings, but only one bright, bright orange building (same colour as the Dutch football team). Head towards it. Hotel Inturprag is attached. The entrance to the hotel is on the side that's closest to you - in a sort of loading bay. DON'T walk up the little hill, there is no entrance on that side.
Despite the unappealing lobby and stairwell, the room I stayed in was a model of cleanliness, brand new furniture, fixtures and floor coverings, including the bathroom. Not a lot of personality to the room, but nothing unpleasant or particularly ugly.
The room was on the small side, but certainly not the smallest I've ever had. You could get around 3 sides of the bed (just) even though the wardrobe door wouldn't open all the way because it hit the foot of the bed.
Despite being in a suburb, it was quite noisy when the windows were open - traffic noise mostly but also what sounded like construction noises. And the walls were thin, so I could hear the television in the room one side of me and the elevator machinery on the other side. Luckily, I'm not too bothered by noise, but if you are - bear it in mind.
A couple of accessibility/safety issues: The hotel says it is 200m from the he Ceskomorovska metro station, but it's quite a bit further. The elevator stops half way between floors - meaning there is a flight of stairs up or down to reach your floor. And though there is housing around, the road from the metro to the hotel is very quiet, and as a woman travelling alone I wasn't entirely comfortable there at night. And if there were nice restaurants or something around, I didn't find them, it just looked deserted, really.
I'd booked a room with internet and a phone, I understand there are less expensive rooms -- these may be un-rennovated, or (even) smaller.. There is also apparently a higher category of rooms. The internet was via a very short DSL cable, but it was indeed high speed, which I definitely needed.
Overall, I wouldn't say I'd NEVER stay there again, but I would certainly look for cost-comparable alternatives that were closer to something a bit interesting.
