The flat is located right in the centre of Prague, so most major places/sights as well as the main train station could be reached by foot within 15 minutes, which was amazing. I also loved the building and the terrace/balcony, with lots of plants, a table and chairs, perfect for relaxing or eating outside.
There were some issues with communication/service, however. When we arrived in the afternoon (past the indicated check-in time at 3 pm) to pick up the key from the key box, the box was empty and we couldn't reach anyone (no reply on airbnb and only an automatic pre-recorded voice when we called the number indicated). One of the employees (?) saw us, made a call and we got our keys quickly after that, but the apartment obviously hadn't been finished cleaning (smudgy mirrors, dust next to the bed, hair on the bathroom sink and almost no toilet paper left). Also, some of the basic equipment for cooking indicated in the ad was missing (e.g. oil, salt). Finally, the Wi-Fi didn't work for the first three days but started working later on.
All of these things would not have been too big an issue if we had received any information about them or just a reply on airbnb, but this was not the case. All in all, the place was great, but we did feel left alone with several of the issues.
