Ricardo was a huge God send for us as we need a place to stay last minute for our last night in Berlin. Check in was easy and the apartment was easily located with the directions provided. Ricardo and his brother were easy to get a hold of and had quick response times. His brother provided us with public transportation directions that was very helpful. We were only there for a night and leaving for the airport the next day so sadly we weren't able to ask or take advantage of any recommendations that they may have had for us. The apartment is a little bit from the main city area but not a long journey via the tram. There were two grocery stores near by that we were able to get food in the morning before heading out.
The apartment was very clean and had all the necessities that we needed, wish we would of been able to stay longer.
