My experience with Frank as a host and his place is positive. We had a specific situation and stayed in Prague for 19 nights, which is not very usual. The place is located in Prague 2, which has great tram and metro connection. The apartment is on a second floor and there is no elevator, but it was not a problem for us. Before your arrival, the host sends you an email with lock combinations and directions how to check in and use the apartment.
There are many little stores in the neighborhood where you can buy food and other products (I think they are called "Večerka"). "Lidl" is 5 minutes away by foot. You can find kebab and pizza restaurant nearby and diagonally in front of the apartment building is a great bar "Boothill". Also - visit Vyšehrad, which is 10 minutes away from the apartment.
Unfortunately I had to go to the hospital, so it is great to know that the hospital is 15-20 minutes away (walkable distance, few minutes with Uber) and that the doctors speak English. If needed, there are many pharmacies in Prague (one is 3 minutes away). Police station is also nearby.
Regarding apartment - we stayed in "Autumn room", which has one narrow wardrobe, one fridge, one bar table and 2 bar stools, one double-bed and two nightstands (with two lamps). The room also has shoehorn and roller for cleaning clothes. You can put your coats and jackets on the hanger on the wall. There are many electrical outlets in the room, which is great. The room has it's safe/cupboard in the hallway where you can store your luggage. The bed has two single mattresses and two sets of bedding. Every guest gets two towels in different sizes.
You are sharing bathroom, separated toilet and kitchen with other guests so you depend on their schedule and cleaning habits. Sound isolation in the apartment is not very good, which for people staying there for a short period of time does not present a problem.
We had a problem with guests who didn't clean after themselves. They would leave their hair, toothpaste residue and spit in the sink and shower, some of them didn't even flush the toilet. One of the guest flooded the bathroom and left it that way. They would also leave their hair and dirty counters in the kitchen. The host did leave noticeable notes and directions how to interact with other guests and use amenities but, as I said, you depend on their habits and upbringing. :)
Plus, as i said to the host, people tend to leave their food hidden in kitchen cabinets and I am not talking about long-lasting products as pasta, rice or condiments. It is probably their good intention to leave their food for other guests, but it would be great if they would leave it in the visible place so it doesn't go to waste :)
POSITIVE: electronic check-in/locks/safe, very nice bathroom in general (spectacular shower with wellness jets and rainfall shower head, great make up mirror, hairdryer, washing machine and detergents), your personal fridge in the room, cosy warm clean bedroom
NEGATIVE: sound isolation, other guests' behavior, WIFI connection is sometimes interrupted
SUGGESTIONS FOR THE APARTMENT: please wash or change the shower curtain, place another more visible note in the kitchen for electric stove use because some of the guests left the stove on multiple occasions on and that is a hazard
SUGGESTIONS FOR THE AUTUMN ROOM: some of the bedding zippers are broken so change/fix them, if possible - put one mattress so that lovebirds can hug in sleep :)
I think that people would not notice all stuff mentioned above in their short stay. This place has a big recommendation from me because of it's costs, location and helpful and understanding host, with whom I shared all my worries and issues :)
So Frank, thank you for everything and I hope you will be very successful in future :)
