I had a great stay at Alena’s place. The apartment is located about 20 minutes walk from the main train station, you can also walk into Old Town Square in about 25 minutes. The apartment is clean, modern and well equipped, it is definitely big enough for 1 to 3 people. They are also restaurants, cafés and supermarkets nearby. Alena was very responsive to my questions during my stay. Highly recommend it for anyone coming to Prague to stay here.
