We stayed for 5 nights in Barcelona with the family. The organisation with Gemma was simple, she replied to all enquiries within 5-10 minutes of sending them through and she was very helpful.
The apartment was lovely and huge for the centre of town, Placa Catalunya was within 2 minute walk and there was a lovely Illy cafe next door. The apartment had everything such as washing machine, dryer and dishwasher. I would highly recommend this apartment for anyone considering travelling to Barcelona!
