What an excellent stay. My girlfriend and I stayed for two nights as part of our three-city tour for her 21st and whilst the city was great, the host and accommodation was equally as good.
Etienne is a wonderful host and has great local knowledge which he is happy to share! His place is modern, stylish, clean and private. It is in a nice location with an array of restaurants in a 10-minute walk and only a 10-minute tram ride from alexander-platz.
Would 10000% recommend this apartment and could not vouch anymore or it!
