Martin and Paul's place is great, exactly like on the pictures. One of their friends was here to welcome us. We are a couple and this was our first experience in Vienna. This place was perfect. Very easy to reach by train from the airport (OBB to Mitte or Rennweg which is closer, then walk for 10 minutes). Around 15-20 minutes walk to the city center but you can also take the bus. Great decoration. Very quiet place in a small street. We do recommend this place.
