Our stay at Klaus’ apartment was great! Klaus was really quick with communication and check-in/check-out were very easy. Klaus sat with us when we arrived and explained things about the apartment and gave us a ton of suggestions for the city. Location of the apartment is perfect - a little noisy at night since there are bars and restaurants close by, but nothing that prevented us from going to sleep. We would definitely recommend this apartment to anyone during their stay in Barcelona! Thanks Klaus!
