Well outfitted studio at a reasonable price. Studio is clean and well equipped, with portable safe, good quality bathroom sink and shower, full fridge, bed, etc. Central to both the Old Town and Jewish Quarter - easy 10 minute walk to each. Located on a main street with other apartment type rentals and shops vs. mainstream hotels and is in front of tram stop. Note there is no service desk on the premises (someone will meet you there at the appointed time to check in and you just leave the keys in the room when leaving) or elevator in the building and need several keys to get into the apartment.
At night there are motion sensor lights in the hall and up the staircases and they go out fairly quickly - less of an issue if you aren't a solo traveler.
Staff is very responsive on email though Hotels.com but would recommend booking tours and airport transfers directly with tour companies as Crownhill add a mark up (10-15% I estimate).
Would have liked there to be better signage at the entrance (only sign I saw was a small one for a "sex shop", with telephone number to call to gain entrance to the building - it's located in the back courtyard, not where the apartments are!).
Overall a very good choice for those wanting kitchen facilities and a reasonable priced option vs. hotels in nicer locations.
