I would highly recommend staying here for a large group. It is very roomy. There were 7 of us (2 couples and 3 singles) and we had plenty of room. It never felt crowded and each couple/person had their own bedroom.
We didn’t use public transport and used a mytaxi app to get to and from the centre. (20 min journey and circa €18-25 )it was super easy and convenient for a group our size. Although the public transportation was easily accessible, as well as a local shop for food and drink.
