Stayed at Cristina's place for 3 days and 2 nights. It was nice, clean and really stylish. The price was also reasonable especially since it was quite central. The place is near the metro station (Atocha Renfe) which was convenient for travelling around. The interior decor was nice, and the kitchen is well-equipped. The place is also near stores, cafés and restaurants. My only minor concern was Netflix not working although it didn't really bother me that much, and possibly the occasional noise. The bed is up the ceiling which you'd occasionally hear people's footstep above it but the bed was super comfy — lotsa pillows! But despite that it was a really nice stay, and would definitely go back / recommend it.
