We only had a very short stay at Lisa's flat (one night), but luckily she was able to accommodate us and it was perfect for our needs. We didn't meet Lisa herself, but spoke to her on the 'phone a couple of times and communication was great (only problems in that regard were caused by us not having a smart-phone or tablet to pick up Lisa's e-mails, but she managed to get hold of us by text).
The flat's in a great location in the heart of the affluent Ostermalm neighbourhood of Stockholm, and is about equi-distant between two T-Bana stations (5-10 minutes' comfortable walk either way). It's also well served for supermarkets, bars and restaurants, and the Ostermalm area itself is lovely to just walk around in general (the beautiful Karlaplan circle for example is a great place to sit and have a sandwich or watch the world go by).
The flat itself is comfortable and peaceful, located overlooking a quiet courtyard at the back of the main apartment building- no noise or privacy issues at all. There's a huge TV with access to Netflix, which we took advantage of to watch a film rather than go out in the pouring rain the night we were there.
Overall we had a great experience staying at Lisa's flat, and found it to be just right for our requirements. Thanks Lisa!
