Me and 10 friends from the UK stayed at Colours in May 2019 and thoroughly enjoyed our stay!
Paul's son Nathaniel looked after us during our stay and replied very quickly to any text messages we sent/calls we made regarding places to go in Malta or minor issues with the villa. The pool and surrounding area is fantastic and we made good use of it during our trip. The villa is also only a 15 min walk away from the nearest supermarket (Green's) albeit down quite a steep hill. The centre of St.Julians is also close, I would recommend using taxis to get to and from the bars, restaurants and clubs it has to offer. By extension, I would recommend using Taxis to get around the island in general; we got taxis to the beaches, to the ferry for Gozo and back from the supermarket when we were carrying heavy items. Nathaniel recommended the "bolt/taxify" app to us which is like Uber, and it worked very well.
The kitchens are ideal for cooking in, with adequate utensils to cook most meals. The mini club in the Yellow villa was brilliant, the speakers are pretty good and we used the area for pre drinks most evenings before going out. The fish and turtles are a cool addition to the villa also.
In terms of clubs, St.Julians and specifically Paceville is v lively. Havanna and the clubs around it are great for RnB/Pop music and free entry, and Skycity is open on friday and saturday nights playing mostly tech-house stuff with an entry fee of 10 euros. Drinks are average priced, around 3 euros for a vodka mixer, 4 euro for a pint of lager.
Overall, I'd say the villa is v ideal for a large group of people wanting to spend their days either relaxing by the pool or out exploring the rest of Malta, and their evenings out in St.Julians enjoying the restaurants and nightlife. If you respect the villa, the outside area and its neighbours like we did you should have no issues.
Thanks again to Paul and his family for looking after us during our stay.
