The apartment itself was very large and spacious, with nice furniture. I had thought the place was clean but my sister said that the room she was in had a dusty floor (the sofa bed room). The building itself smelt very bad - we think there was a drainage problem, which made walking up and down to the flat not such a pleasant experience. The lights in the hall didn't always work either. The drainage smell was also an issue in the flat itself, mainly in the entrance room. The building is very old so maybe it can't be fixed. It does however impact on a stay. The two bedrooms are street facing and it is not double glazing so bring earplugs unless you are impervious to noise. There are also no curtains to block out light, so again you'd need an eye mask unless light doesn't bother you. The main thing that bothered us was there was no door to the main bathroom with shower cubicle, so no privacy, and it was connected to the room with sofa bed. As the sofa bed was opened, it blocked the doors so they couldn't be shut, so no privacy there either. It would be better if just the two bedrooms were used, then the sofa bed would just be a sofa and you could shut the door, giving privacy to the bathroom too. They need to install a bathroom door, and also get a smaller sofa bed.
In general we slept well and it was a fab location and looked nice, but these things need to be addressed to make it suitable for more than 2 people or 2 couples.
