Pros: Good location, everything you need is close by. Great communication from the hosts, very quick replies. Apartment is great for a group, with rooms off a central hall and a great main lounge and dining room with nice views of the square. Lovely at dusk with the sunset.
Cons: Apartment obviously was renovated at some point in the past but maintenance since then has probably been spare. Little things like soap platforms in showers coming away and scrapes and rough edges in rooms. Probably won't affect most people but if that stuff matters to you keep it in mind when booking.
Before check out on the morning we were leaving the next group through walked in to the apartment having been told they could arrive early, even though we had told the hosts we would leaving at the check out time. One of them even walked into my friends room while he was getting dressed.
My friend also found his bed had some sort of insect invasion and he woke up with a number of bites on his body.
To be fair the hosts responded quickly and apologised via messaging. Arguably the response could have been more effusive ( I would be shocked ans extremely embarrassed if this happened in my airbnb) but it's not something that particularly worried us.
In conclusion it's the little things that let this apartment down ( would be great if there was an iron avaliable for example) but if you're looming for a big place for a group with close access to the metro etc then you should at least consider it. Ultimately we enjoyed our stay, but only with sone caveats.
