I spent one night in this gem of an apartment. The location is unbeatable, right in the centre of the city and with double glazed windows so you don't hear the happenings in the bars and restaurants below. The apartment itself is beautifully furnished and spotlessly clean. The bed is very comfortable and there's decent air conditioning.
The Wi-Fi connection is very slow, not suitable if you'll be relying on free internet.
I appreciate that it's an old building. You get an onslaught of information to digest before checking in. Also there are a few details to think about like turning on/off the water heater for the shower, not throwing tissue in the toilet and how to check out, so it makes sense that there is no self check-in.
Even though this reduced my check-in flexibility just a little, I was able to check-in within 30 mins of writing the hosts and Evan was very friendly.
I'd definitely stay here again and I'd recommend it for the lovely experience.
