The reviews are absolutely correct on Nicolas' place. We stayed there for 3 nights and it was amazing.
Nicolas even was kind enough to check us in a few hours early, as we were in arrived early to the city.
He checked us in personally and even carried my wife's suitcase up the 77 steps for her. The steps were a non-issue for us and even welcomed as we had some big meals in Barcelona and the steps helped us "work it off". Haha.
He gives a folder of his personal recommendations for the city and they lined up with the stuff that we wanted to try in research the city prior. Very helpful for those not doing their research.
The place was spacious, well designed and decorated and very clean.
We simply couldn't have been more satisfied with our stay as we rounded out a 2 week trip through Europe.
Highly recommend!
