This apartment and its management were wonderful, and we could not be more satistifed with our experience. Everything had just that little bit more that made our stay special. Some notes on the extras/special touches:
Apartment: had Netflix (!), tons of towels (several each of body, hand, washcloth), plenty of clothes washing liquid AND fabric softener, very clear instructions for the washer, storage shelves in the bathroom for toiletries (not just a pedestal sink and nowhere to put anything), travel-size upscale bodywash/lotion/shampoo and small things (Qtips, etc), tons of dishes/silverware (so we only had to run the dishwasher once during our stay), pod coffeemaker WITH lots of pods, welcome gift and a few beverages in the refrigerator. Furniture was super comfortable (cozy throw, pillows too) and kitchen had everything to clean easily. Balcony in main bedroom lovely to sit on and second bedroom very quiet (and quiet from rest of apartment). Elevator was really handy, and doorman/concierge was friendly. Stall shower in first bathroom was wonderful (no stepping over/into tub).
Communication: could not be better. Stuart made sure that everything was set before, during and after our stay. Any messages sent were responded to within hours. (The person we met when we arrived of course went over everything in the apartment and talked about local sights.)
Location: steps from Old Town Square, literally 2 minutes walk. The location was perfect. As the bedroom windows faced inner courtyards, it was still very quiet for sleeping. Many great restaurants, sights, a Metro stop, tram stops, etc. within 5-10 minutes walk. Note: fantastic bakery (Bakeshop) a 10 minute walk east which is convenient for breakfast items.
These things were in addition to everything you'd expect in an apartment. Thank you to Stuart and everyone that made our stay in Prague special!
