The flat is extremely well located and convenient for catching a bus or train the next morning. I arrived at 10pm and so I didn't really see much of the flat but I chatted with Pilar and she seemed very friendly.
The room was clean and comfortable and had I stayed longer, it would have been a nice place to stay.
There was an issue when I came to leave at 6am though as all the doors were closed and looked the same meaning I didn't know which one took me to the front door. Consequently I woke Pilar up(my apologies). Also, check you can get out the building door in advance as this also proved a problem. As long as you have done it in day light though, this shouldn't be an issue.
