We had a comfortable 10-day stay at Klaus' flat. Pros: it's in a great location, convenient to lots of interesting neighborhoods and just off the Rambla yet surprisingly quiet and calm. Placa Reial is an inviting square. It was nice to have a lift to manage our suitcases. We used the kitchen every day to make breakfasts and we had the supplies and appliances we needed -- it was nice to have a dishwasher. Also great to have a washer and dryer. The place was clean and tidy. We appreciated being supplied with some fruit, biscuits, and coffee. Cons: There were some noise disturbances from neighbors in the building, but Klaus did intervene and it was quieter after that. Also, the wifi did not work well in the bedroom farthest from the modem. Overall, I would definitely recommend this apartment.
