This flat is undeniably beautiful. The rooms are large and the ceilings are high. Plus it's in a great location. We were very happy to stay in such a lovely flat.
The double bed is comfortable and then there are two single beds in the other room. The bedrooms and living room are definitely the highlights of the place.
The hosts will tell you this, but the flat gets noisy because it's an old building. It mainly seems to be the pipes and heating but it woke us up a few times, so ear plugs might be an idea. It's ironic, since the hosts are adamant about not making any noise that might disturb the neighbours.
The kitchen is small and tucked away (which may not suit everyone) and although they're good enough to provide tea and coffee, they rely on guests to wash up everything they've used. This means that many cups were stained and not very clean. I'd recommend getting a cleaner to do that once in a while. It's not much of an extra expense. The plug for the microwave in the kitchen also seemed a bit dodgy. That should probably be looked at too. These things weren't a major issue, but probably make the place unsuitable for a longer stay.
The bathroom was nice and clean and some essentials were provided. The only problem with it is that the extractor fan was pretty ineffective, so smells/ steam tend to hang around.
Any drawbacks are relatively minor and easily fixable, since the flat is wonderfully decorated and very stylish. Great place!
