This is a big, clean, quiet apartment in a spot of town that is super-convenient for the major tourist sites. The value is stunning at the price. HOWEVER 1) the building is mixed-use, and some parts of the stairwell are not lit at night; 2) be aware the apartment is on the fifth or sixth floor (European/US counting), not the fourth, and the door will say "1" not "1A"; and 3) the hot water fuse will be off until you turn it on (or take several cold showers, like me, first).
Seriously, the value for any experienced traveler is great. But the listing needs a few fixes before it will be fully realized.
