We all really enjoyed our stay in Holger's apartment! The location was unbeatable and the space was perfect for our group - open plan communal area with private bedrooms for everyone and plenty of bathrooms. The person who met us at the apartment was very friendly and accommodated an eary check-in which was hugely appreciated.
The only slight things which could have been improved were that there was a noticeable amount of lost property in the kitchen cupboards, there weren't enough loo rolls for the group for the period of time stayed and there were no pods left for the coffee machine, despite the photos showing pods. There is a 24hr shop next door though so this was easily solved.
Overall we had a great stay and would recommend this apartment to any groups travelling to Barcelona.
