Beautiful space in what appears to be a newly converted unit. The whole space is just lovely and a very good location. We would have no problem in recommending this appartment. The location was perfect for us as we like to walk. We were only 20-25 minutes fro Alexander Platz where there are plenty of shops, bars and restaurants. from there you can easily walk to Museum Island and on to Unter Den Linden. Most places are within 1 hour of the appartment although some you will have to take a tram or U Bahn.
We did have a few issues which we are sure Celly will sort out, nothing major which would stop us recommending the place. I will list them here just so you can see that they have improved. There was no hairdrier (you can tell this is a mans appartment), also no cups so we had to make coffee in glasses. The kettle did not work so we had to boil the water in a saucepan. A previous guest stole the TV controller so this was not usable.
We would suggest a shelf in the shower (which is great by the way) for shampoo and shower gel this is not so important but would be a nice touch. What really is lacking though is a guest reference book with recomendations for restaurants, good bars with or without music, palces of interest, map etc. I realise that even if this is supplied it may well be stolen! But a ring binder with paper slipped in could easily be replaced.
One last tip, do not rely on the R7 to get you back to the airport, we got this from the airport without a problem but the return today was a nightmare. Our early train was cancelled and the next one stopped at the next station. We then had to wait for the S9 but our ticket was not transferable. We go to the airport just in time, by the time we got through security and got to the gate we had 5 minutes and we boarded. No one in the sttaion knew why the R7 was not running!
