The location of the apartment is amazing and we loved how close we were to everything in Madrid.
We were disappointed though with the state of the apartment itself with regards the cleanliness etc. Not only was the apartment not cleaned before we arrived (despite checking-in late in the afternoon), there were areas that were not cleaned at all, especially in the bedroom where we found long black hairs under the bed and lots of dust.
The kitchen glasses and utensils were also not clean and should have been checked that the previous guests had cleaned them.
It wasn't a disaster, but it took the edge off turning up to an apartment where the beds weren't changed and there was rubbish everywhere from the previous guests and the rest of apartment was tired and not clean.
