We were a group of 10 but then numbers dropped down to 6. Paul was very helpful and arranged a partial cash refund upon arrival. We found that the sofa beds for the other 4 people, if they had come with us, were not the most comfortable and there were no curtains to block out early morning light in these sleeping areas. Perhaps this is something that could be added? Yes, 10 people can definitely sleep here but less comfort and privacy for 4.
The hot tub was great, in this hot weather (33-38 degrees) we found that we didn't need to heat it up for very long (maybe 2 hours) to get it to a good temp. On the first day it wasn't working, but Paul came out quickly on a Sunday evening to fix it for us.
From other reviews we thought it would be better quiet in the garden. Daily you can hear music from a bar nearby, and in the evenings you can hear people in a bar above you. But, the surrounding walls are high and you can only hear it when outside. We found it added to the holiday feel, but it did start up around 9am which may not suit everyone. Inside is fine, can't hear anything.
The location is great, 1-5 minute walk to anything useful (various supermarkets, ATM's, clubs, beach, buses).
The apartment itself is beautiful and has lots of things that you need. Remember to turn on the shower buttons early if you want showers, even cold ones - this controls the heat but also water pressure, which we didn't realise.
Very helpful host, has a good network of people to assist in your needs. Really enjoyed ourselves once we settled in and started to discover Malta!
