The apartment was PERFECT, light and spacious with postcard-like views of the city from the huge living room window and openable skylights - we took a few dozen pictures before we even left to explore the city. The bed was cozy, with two skylights right above to let in light and air if you wanted and blinds to close otherwise. The shower was nice, but the tub - more like a small jacuzzi, with jets and bubbles - was the perfect way to end each day. The whole place was clean and light and could have accommodated two couples easily, but for two people it was comfy and romantic.
The location was great, a 2-minute walk from both Namesti Republicky and Starometski Namesti. Metro stations are a block away, but we never used them... no need. A huge store and shopping mall is a few minutes away, with little markets and restaurants at every turn. A friendly all-night quickymart, a minute from our door, let us stock up for the next day as we walked home each night.
We had asked if we could leave our bags a few hours before check-in; Eli met us early with the news that the cleaners were already done and the room was ours. Eli showed us around the place, including pointing out the little fridge we hadn't expected and probably wouldn't have found. She gave us her contact info in case we needed anything during our stay, but we didn't need it - no problems, no hassles. Eli was friendly and informative, providing maps and info about tours and restaurants and offering to set up additional tours or transport if we required them.
The TV, normally something we would ignore, could make Bluetooth connections to our phones and tablets... playing our music and slideshowing the day's photos each night was great. (It was like having a Chromecast or AppleTV built-in.) The WiFi signal was very strong and reliable.
We thoroughly enjoyed our stay at Rob&Eli's apartment... the only thing we didn't like was that eventually we had to leave. We will definitely look up Rob&Eli when we return to Prague.
