We really enjoyed our stay at Charles's place! It's close to the airport but also just a short train ride to the city which was perfect for us. Charles always replied very quickly and was very helpful with everything. The apartment is very clean. The only thing that we didn't quite enjoy were the beds because the mattresses are very hard and at least the bed that I slept in was very squeaky so the sleeping quality wasn't the best. It's definitely okay for a few nights though! I can only recommend this place :)
