Never had any issues while I was a client, appart from being the smallest gym ever. However and just a warn to everybody, they are thieves. When you cancel the contract, they don't tell you or make clear that when you cancel you have to give a month in advance. In my case: I canceled my membership on the 6th of January (even though I paid for the whole month on the 1st of January) and they will still charge for the month of February, even though it's cancelled. This is absolutely ridiculous, specially if you don't tell your clients and the modality is no contract!!
Hope people see your reviews here before you try to scam more people.
