Lukáš and Hana’s apartment is really well put together; it has all sorts of personal touches that makes the space homey and practical. The kitchen is well stocked with modern appliances. If the weather is nice, you’ll love sitting on their balcony looking over the old town. If it isn’t, you can use their comfy bath. The location is absolutely stellar for tourist activities— the Klementium’s Baroque Library and astronomical tower and the ornate Charles Bridge are just 2–3 minutes away; and the castle, Charles University, Jewish Museum, Narodni Museum, and islands in the middle of the river are all quick walks (~10 min or less).
The only issue I had had to do with the otherwise great location: it can get pretty loud at night, especially Thursday through Saturday. One night was filled with drunk Austrians singing and yelling until sunrise. But I think this is probably an issue for any accommodation in the old town. And it won’t be a problem for anyone who plans on staying out late—but it was for me, since I came for work and am a light sleeper. Luckily, the apartment has a fan and water cooler, both of which are good for making white noise. That helped a lot.
