We were very happy with our stay in this apartment. It is extremely bright and cheerful which helped offset the grey and dreary weather for our week stay in Berlin. Leon was very attentive and answered our messages with no problems.
We were met at the apartment by his mother who showed us around and gave us the keys. (The only thing we wished we had was 2 sets of keys. Travelling with friends, we had to do a lot of organizing to make sure someone was at home to let the others in)
The apartment is clean, modern and had everything we needed. The beds were comfortable and the location was perfect for our never ending day trips out into Berlin.
I would definitely recommend this apartment for everyone. A small group of friends or a family.
