Pro: Great location. Walking distance to St. Peter's Church, you can hear the bells from the flat! All you need (grocery, restaurants, T-shop to buy bus tickets) are all within walking distance. Easy access to public transit to all sites, train to airport, etc.
Con: The flat needs repairs & a very, very deep cleaning.
Pro: The host is warm, helpful and responsive.
Con: You can hear some noise from the flat above in the evening.
Pro: Very, very quiet otherwise! Lovely view from bedroom window into building's tranquil private garden.
Con: Privacy. You can't close the curtains and have the AC/fan on as it would block air flow. The AC unit is not portable.
Pro: Well equipped with cleaning materials, kitchen items, and hair dryer.
NB: The bathroom shower drains via the floor (there is no stall, just a curtain) & water temperature was tricky. I ended up turning the water off while soaping & waiting for the brief 30sec or so of hot water to rinse off in. This also prevented too much water build up on the floor if you like long showers. I would recommend bringing your own toiletries.
The flat is good for a short stay for 1-2 people. My biggest con was that the flat needs love & attention: repairs & in-depth cleaning. If the host put some elbow grease into it & upgraded a few items, I would stay here again and recommend it.
