Alberte's flat is fantastic for a couple. The location is great and only a short walk from the main city centre and also the M1/M2 metro lines and, what for us was a great find, the "water taxi" which runs from very near the DAC.
The Sushi place, Hatobi, just across the road from the flat was lovely and I'd recommend this.
Alberte herself was very accommodating with our requests and was very prompt in responding.
