We stayed for a month in Mary’s apartment during winter and overall are quite happy about it. The location is magnificent - at walking distance to all the major sights and attractions. The apartment itself is super spacious and probably dates back to medieval times with high ceilings and original wooden beams. The charming cobblestone alley it’s in is too narrow for car traffic which is great - not much street noise. Great restaurants galore at a leisurely amble. The place can be comfortably heated in winter and the wifi is pretty reliable. Mattresses are nice. Washing machine, oven and fridge/freezer function as they should.
The drawback is that the place hasn’t seen much investment recently and it shows. Whilst very spacious, the bathroom is rather archaic and has a tiny shower with limited hot water. We tried using the dish washer once and it instantly flooded. The antediluvian vacuum cleaner weighs like a hundred pounds and makes a terrible noise but doesn’t clean very well. There weren’t any usable pots and pans in the kitchen and neither was there a mop but Mary kindly provided them in the first week which was helpful. Furnishing is functional at best, but does the trick. Tap in the kitchen isn’t reliable. The cover is peeling off the iron board. Upstairs neighbours are crazy.
So overall a positive experience and would defintely recommend (especially for short stays), but with some modest investment the place could be a real gem.
