We stayed at Maya's for 7 nights. The location is really great, the U-bahn station, train and busses are right across the corner, a 3 minutes walk. We had coffee shops, few bars and a lot of places to eat.
The apartment's located in a back yard, it's a very quiet and calm area. Maya's flat is very nice, cosy. Our room was comfortable and was all a couple visiting Berlin would need. The bed was good, but I must say- if you are a person who's used to sleep on a hard mattress you might find this one too soft for you. Maya has two cute dogs which we liked very much.
All in all, a nice stay, we really didn't spend all that time in, just went out in the morning and got back basically to sleep at night. The shower was clean and nice, the house is clean and welcoming.
Thanks Maya!
