I have a totally fantastic experience to staying at Manuela's space. Her flat is super clean and tidy, stylish, comfortable. You can find everything you need. Manuela is a very kind and engaging person, she answers in short time. She can recommend you local event possibilities etc. You should just ask her.
Manuela's flat is well located, close to turistic places, railway station, shops, restaurants, bars - everything in 10-15 minutes on foot. At first glance the neighborhood probably seems not nice but if you take a little time with discovering the streets you will realise it is fine. :)
The nights are noisy because of the location but if you close the windows and use the air conditioner (and maybe a earlplug) you won't have any problem. I had restful nights but I think every traveller have to consider this stuff on their own.
The only shame is that I hadn't got more time to talk with Manuela. I guess she is a very interesting person. :)
