We were a group of 7 people that stayed in this apartment during New Year's and had a fantastic time.
1. The location is great. It's easy to get from here to almost all relevant touristic locations in Prag within 10 - 20 minutes walking. The main trainstation is 10 minutes away. There are bakeries and grocery stores close by (5 minutes walking distance). The same applies to a few bars, restaurants, and escape rooms. The view from the Narodni museum during New Year's was incredible.
2. The size is great for 7 people. The apartment is very spacious and has 3 separate rooms and two bathrooms. We were 3 couples and 1 single. I think though that the sleeping couch for the 1 person might be a bit small if the person is larger than 1.80m, then its better to be just 6 people.
3. Facilities & Furniture are good. The table can fit 8 people and there are 8 chairs available. The kitchen is decent for cooking simple things (e.g. we made pizza for dinner & bacon and eggs in the morning).
Overall, we had an amazing time. Thanks for letting us stay!
