Longer version:
The location is fantastic - peaceful, next to a park, safe, and only a couple of minutes' walk to the nearest public transport stop. We parked our car at Mr. Parkit's garage on Španêlská 12, close to the apartment. The host is very kind and caring, has great recommendations, is very responsive, and is at your disposal the entire time of your stay. The apartment was clean, cozy, and spacious. There was no problem with check-in and check-out whatsoever; the details provided were descriptive enough, and the platform the hosts use for all formalities needed for your stay in Prague takes care of everything. We each got our own towels, and the host surprised us with traditional Czech mead.
