I do recommend the appartment and the hospitable owner - Pablo. The flat looks the same on the photos as in reality. There is all stuff required and needed, additional covers also (at the end of April/ beg. May the nights are still chilly thus I recommend you to take socks and pijama with long sleeves if you like to be warmed up. :))
The location is very good. Only 3 min. walk to Park Guell, ca. 7 min. walk to underground station. From that place you can also reach the city centre by walk along one of the best avenue in Barcelona.
The owner was also very helpful with all the hints and also with organising a transport/taxi from/to the airport. All the best! Thank you. :)
