The location of the apartment was really great, close enough to the old city to reach it within 10 min. by walk, but also distant enough to avoid the noisy crowd present at the old city (during Christmas holidays the city is really invaded by tourists). The apartment is perfect up to for 4 people (big beds and spacious bedrooms). Close to the apartment there are not supermarkets really well furnished, so better plan a day to buy meals. Otherwise, the zone nearby is plenty of restaurants with affordable prices and nice cuisine. Sarah, Matthew and Silvia have been always very attentive and easily reachable via whatsapp. They also have created their own guide of Prague very usefull with a lot of tips (restaurants, places, advices on transport, etc). I would recommend this place as a "pied à-terre" to visit Prague as is very close to the old center by foot.
