The flat is really nice with original features like the beamed ceilings and tiled floors, mixed with modern bathrooms and a functional kitchen. Location is good - bit dull downstairs, but 10 mins walk to where it all happens. The equipment provided is fine: table to dine, chairs to sit and tableware to use. Shower and face towels are provided (shower towels of a small size, but you'd get the same in an Ibis hotel) and yes, thanks, a rug too. Communication was good throughout and check in/check out smooth.
We did have some issues though, main one being an unbearable sewer smell affecting the communal stairs. Luckily, with the door shut, it mostly stayed out, but it prevented from opening e.g. the bathroom windows for aeration. We were in Barcelona on the coldest week of the year and the air conditioning system was struggling to heat up the whole place: rooms were about ok, but the living room was quite cold. Lastly there was a little dust here and there and the linens had probably served their time. Oh and no headboards for the bed - seems trivial but they transform a "mattress on a frame" into a "bed"...
Overall, I went there on a business trip on the busiest week of the year, paid a nightly rate that would normally get me a deluxe room in a Hilton and on those terms I was disappointed, however on a more leisure trip on a budget the accommodation is more than adequate. Still I think that a few tweaks here and there would be required to live up to the potential of what essentially is a nice flat.
