What a wonderful place in a perfect location. Place is perfect if you plan to do a lot of sight seeing, eating etc. Flat is situated on a lovely, mostly pedestrian road. Close to museums and must-see locations but off the tourist track. Most of the bars are filled with locals. You won't even be able to visit all the tapas places in the area there are so many.
Place is very clean, very safe and has a lovely window open to the quaint street below. I didn't spend much time in the flat but when I did it was comfortable and very nice.
Can't recommend this place enough!
