I like staying at Rick's place. The place itself is very spacious and within walking distance to all main tourist attractions in Old Town. Its retro-styled decoration also gives out a sense of nostalgia and you can enjoy his vintage collection.
Rick is a wonderful and attentive host, always promptly responding to your requests, and a very open-minded hippie. We did not start on the same page at the beginning for we thought we got 2 rooms for the stated price (which in fact we needed to pay extra), however, things got cleared in the end and he even helped kept our luggage while we traveled to another city.
If you expect a nostalgic, retro, unique place to stay in the heart of Prague, Rick's place won't disappoint you. But if you expect something brand-new, modern, this is probably not the kind of place for you.
