Fancy a nice city break - then head to Krakow in March for 2 nights for just £61.54 pp from Bristol. It should start to warm up a little in March, and I really do recommend visiting Auschwitz and the salt mines. If you have time, the free walking tours in Krakow are worth giving a go, particularly around the Jewish quarter area as the guides really are a good source of information, as well as recommending some hidden gems in relation to food too.
The hotel is the Ibis Krakow, which comes highly rated with it being in a central location and walking distance to most attractions too, ideal for exploring the city on foot and near to the train station too for exploring.
2 nights in the Ibis Krakow Stare £35.12 book directly on Accor website.
Flights 8-10th March £87.96 for 2 people.
Total price per person £123.08/£61.54pp
Flights are RyanAir.
Nice find OP - As I was browsing, you can also get the 8th-15th with the flights for £79.96 and same hotel for £174.25, so £254.21 (£127.11pp) for a 7 night option which is only twice the price of the 2 nights :)
