Location, location, location! It trumps everything else. You couldn't find a more central accommodation. It's within walking distance of many major attractions, it offers quality dining at affordable prices and it's less than two minutes to the metro.
While it is a modest space; if you're like us your out in the morning and back at the end of the day, ready to crash for the night. Because of the flat's size, a futon does double duty as a sofa & bed. The cushion was relatively firm. It must have been “queen size;” it fit two comfortably.
One of my key markers is the shower. This one is top rated; it had a quality shower head and plenty of hot water. On the other hand the bathroom sink is an ornament. I used it to get a glass of water, but I used the kitchen area sink for hand washing and brushing my teeth. TP: high marks; some places provide wax paper!
We didn't use the kitchen but it looked like it was adequately equipped. The place was well lit, bright in fact. To me saving money using 40 bulbs is counterproductive—dingy does not work.
My one nit concerns bedding. Maybe it's an American thing; I'm used to a top sheet. This flat (and the one I'm in now, in a different city) only provides a fitted sheet and a duvet. I wonder whether the duvet is laundered with each turnover? If not, it raises public health concerns for me.
Bottom line: Can't beat the location!
