We had a great 3 weeks stay in April at Barcelona this year. The communication with Peter in advance was easy-going and helpful. Peter was very friendly and took care of all preparations. When it came to the trip, he was there punctually and gave us a super introduction to the flat and its electronical devices. He even prepared some utensils (toilet paper, etc.) for the first day. When we had a question during our stay and contacted him, he replied immediately and successful.
The flat itself is bright, its design very stylish and modern. Everything was super clean and we were missing out on nothing. The location of the flat is very central in Barcelona and easy to reach from the airport. The area is not too much overcrowded by tourists (like gotic) and has a very familiar atmosphere.
Concluding: No problems at all - POI´s are in the near reachable by feet - and everyone can trust Peter and his doing.
