Studio Golem has a great layout - perfect for a travelling couple like ourselves. All the amenities were there including a safe, which is a great touch for travellers who don't want to carry their valuables around with them. Comfy bed, working kitchen and above all else a VERY central location to get to all the Old Town sights (5-8min walk).
There is a maid service that came every day to clean and make the bed, which is a nice touch. Wifi is super fast too.
Only thing to note: it is on one of the busiest, touristy streets of Prague so it gets very loud especially at night. If you are in Prague for the nightlife, then it probably won't matter. However, if you are out sightseeing during the day and need sleep, it does get quite loud until 1am but this is the only disadvantage. Being in heart of Old Town does have its perks too!
