We enjoyed our stay in Gozo at Tel Fenka - we were 7 people altogether and found the accommodation big enough and comfortable for all of us. It's very quiet, but be aware of the loud fireworks in August. The kitchen is well equipped for cooking and the outside space is nice for eating al fresco. You are situated in a farm area, so the smells are not always pleasant.
We had an unfortunate problem with the pool which affected our overall stay negatively. On day 3 of our 10 day holiday, the pool became murky and unfit for use. We let the owners know on many occasions and whilst responsive by email, the problem was not resolved satisfactorily. They assured us it would be looked at and after several back and forth emails and maintenance visits, the pool was finally cleaned....but not until the day we left. So our holiday in the sun was spent without a pool as planned.
