The first thing to say about this place is that it is not in the most safest or touristy area and when you arrive at night it can create a bad first impression. Saying that, we felt very safe and relaxed here for most of our stay. The only blip was on our last day when we saw an old man get mugged by a gang in front of our taxi just down the street from these apartments. Before this, we had felt completely fine walking around during the day. These apartments are very close to the historical centre and only a $4 (max) taxi to the new town. We had wanted to experience the 'real' Ecuador and these apartments let us do that, but with everywhere you go you have to take the rough with the smooth.
All the tourist advice says to get a taxi for short disatnces of a night time and, when following this advice, we were fine. Although there are not many taxis that pass by here so you will have to walk to the corner to flag one down unless you get the Easy Taxi app. We found this very hepful as it avoided the walk of a night time (taxis come straight to the gate) and the awkward phone call to order a taxi (we don't speak great Spanish and not many taxi drivers speak English). No taxi drivers will know where this is so make sure you take some kind of map out with you so that you can show them where you want to go for return trips.
Although there is no getting away from the city noise at night, the garden area is very peaceful and beautiful, and the views of the city and mountains were good from our apartment.
Overall, we would stay here again and would, and have, recommended this to friends. If you stick to the tourist guidelines you shouldn't have an issue.

We enjoyed 4 nights at the Garden Suites to kick off a month in Ecuador. Firstly, we appreciated the airport pick up so much. We arrived in the middle of the night to find our hosts had supplied food in the fridge for breakfast the next morning. Our multi-level suite was spacious and immaculately clean. The bed very comfortable and well supplied with cozy bedding for cool, damp Quito nights. Our host Wolfgang was a wonderful resource for advise on how to see the sights.

We stayed in suite Estrella, there's nothing I would change or modify in this private condo, every thing has been designed and placed well-thought-out.
Our hosts Wolfgang and Andi were helpful since the first email all the way to our departure. Wolfgang recommended places to see and we were glad to have met our wonderful taxi driver Cristian.
I wish I had stayed there longer... but I will go back, definitely recommend this rental to anyone traveling to Quito.
