Paula's place is perfect to stay as a couple in Madrid. It is a beautiful building with a really nice rooftop terrace. The location of it is perfect - not only beautiful area but also close to major attractions of Madrid.
Communication with Paula was very easy and even though we didn't get to meet her, the check-in and check-out were really simple!
The only drawback of this flat was for me the Internet. It was quite slow and dropped connectivity frequently.
Would definitely come back there again and recommend to anyone visiting Madrid! It's a place with a 'soul'.
