Me and my boyfriend stayed at Diego's place for 3 months.
We can totally recommend his apartment for long stays visit since it is equiped with EVERYTHING you will need (kitchen is fully equiped, washing machine, private toilet, huge bedroom with enough space to exercise if you are really into it etc). Diego is really fun and easy to live with but most important, he is there when you need to ask him something or you need help with something in the house. Diego's kids are really sweet to hung around and if you need your space you can always go into your room and relax. WiFi has good signal through out the house but the speed sometimes is a little bit slow.
Only minus I can really think is that the house is on the 3rd floor without any elevator, so you will exercise everyday even if you don't really want to.
It was a beautiful stay after all. Thank you Diego. Greetings from Greece.
