The house is new and quite stilish, though as most houses in Barcelona not very bright (windows are present only in the main dining room). Overall it was clean and organized, including bathrooms which are very very small but functional. Shampoos, coffee, water and a small cleaning set were provided upon our arrival and this was a plus!
The check in process and the assistance provided by sweet inn were smooth and efficient.
Note about the area: not the most lively in Barcelona but metro is really closeby, if you’re looking for movida probably you need to move a little bit further. The upside is that the area is quieter than other ones and less noisy.
Finally I think good quality-prize balance.
