My parents stayed in Sarah´s apartment in Barcelona for almost a week. The place is incredible, it is very nice decorated and equiped.
Normally walks in Barcelona are long and tiring, but Sarah´s flat has probably the best location so it's easy to move around and do sightseeing. It is located on a very central boulevard - have in mind that it can be busy during the night.
Sarah was a great host, although my parents don't really speak English or Spanish, I believe they had good connection during the stay.
Thank you for everything!
