Hi Franziska,
My family and I would like to thank you for the beautiful time we had in Barcelona. Your apartment is located very well. We were able to reach two different metro lines (one at 5 mins walk and the other one 10 mins walk), we had plenty restaurants and supermarkets close by. We really enjoyed our stay and when we come back to your city, we will be looking for your apartment again.
Moreover, Ivan (your employee) gave us great tips on where to eat and to go out. He was amazing.
Sincerely
