We rented Martina's place for a big family gathering abroad and the place was surely big enough to accommodate us 9.
Everything was sparkling clean, quiet and well decorated. Tha flat is 10min walk from the main square which makes it really convenient to explore without the drawback the noise yu usually have in the hyper-center.
Finally, Martina could not be more helpful! Early check-in, Taxi booking, recommendations: we made sure we had everything to have a wonderful weekend.
If you are going in Prague, we highly recommend staying in that lovely flat.
