My experience was good, but could be a lot better. Charlie's building has a nice structure, but a lot of things could be improved. Regardless the room was clean, there are a lot of holes on the walls, the hot water does not work always and there is no doorbell or intercom system. The arrival is really bad without doorbells or intercom, knock in the door does not resolve the problem because he lives on the first floor. The best way to communicate with Charlie is by Whatsapp, but if you don't have mobile internet this is really hard.
So, the it's a cheap option if you don't care with waiting to get in or unstable hot water, this is good.
